Tham Luang Nang Non Chiang Rai Bangkok Location within Thailand

In June and July 2018, a junior association football team was rescued from Tham Luang Nang Non, a cave system in Chiang Rai province, northern Thailand. Twelve members of the team, aged 11 to 16, and their 25-year-old assistant coach entered the cave on 23 June after a practice session. Shortly after they entered, heavy rainfall began and partially flooded the cave system, blocking their way out and trapping them deep within.

Efforts to locate the group were hampered by rising water levels and strong currents, and the team were out of contact with the outside world for more than a week. The cave rescue effort expanded into a massive operation amid intense worldwide public interest and involved international rescue teams. On 2 July, after advancing through narrow passages and muddy waters, British divers John Volanthen and Rick Stanton found the group alive on an elevated rock about 4 kilometres (2.5 mi) from the cave mouth.

Rescue organisers discussed various options for extracting the group, including whether to teach them basic underwater diving skills to enable their early rescue, to wait until a new entrance to the cave was found or drilled or to wait for the floodwaters to subside by the end of the monsoon season several months later. After days of pumping water from the cave system and a respite from the rainfall, the rescue teams worked quickly to extract the group from the cave before the next monsoon rain, which was expected to bring additional downpours on 11 July. Between 8 and 10 July, all 12 boys and their coach were rescued from the cave by an international team.^[9]

The rescue effort involved as many as 10,000 people, including more than 100 divers, scores of rescue workers, representatives from about 100 governmental agencies, 900 police officers and 2,000 soldiers. Ten police helicopters, seven ambulances, more than 700 diving cylinders and the pumping of more than one billion litres of water from the caves were required.

Saman Kunan, a 37-year-old former Royal Thai Navy SEAL, died of asphyxiation during an attempted rescue on 6 July while returning to a staging base in the cave after delivering diving cylinders to the trapped group. The following year, in December 2019, rescue diver and Thai Navy SEAL Beirut Pakbara died of a blood infection contracted during the operation.^[10][11][12]

Tham Luang Nang Non is a karstic cave complex beneath Doi Nang Non, a mountain range on the border between Thailand and Myanmar.^[13] The cave system is 10 kilometres (6.2 mi) long and has many deep recesses, narrow passages and tunnels winding under hundreds of metres of limestone strata. Since part of the system is seasonally flooded, a sign advising against entering the caves during the rainy season (July to November) is posted at the entrance.^[14]

On Saturday 23 June 2018, a group of 12 boys aged between 11 and 16, from a local junior football team named the Wild Boars, and their 25-year-old assistant coach, Ekkaphon Kanthawong,^[15] went missing after exploring the caves. According to early news reports, they planned to have a birthday party in the cave after the football practice and spent a significant sum of money on food, but they denied this in a news conference after the rescue.^[16] The team was stranded in the tunnels by sudden and continuous rainfall after they had entered the cave system.^[17] They were forced to leave some food supplies behind when fleeing the rising water.^{[18][19][20][21]}

At around 7 pm that evening, the head coach and founder of the team, Nopparat Kanthawong (Thai: นพรัตน์ กัณฑะวงษ์), checked his phone and found about 20 missed calls from parents worried that their children had not returned. Nopparat dialed assistant coach Ekkaphon and a number of the boys, but he was unable to reach them. He eventually contacted Songpon Kanthawong, a 13-year-old member of the team who said that he had separated from the team after practice and that the rest of the boys had entered the Tham Luang caves. The coach raced to the caves, finding abandoned bicycles and bags near the entrance and water seeping from the muddy pathway.^[22] He alerted authorities to the missing group after seeing the team's unclaimed belongings.^[23]

There were 12 children and one adult trapped in the cave, as follows:^[20][24]

At the time of the rescue, the assistant coach and three of the boys had no nationality. Head coach Nopparat explained that they are from tribes in an area known as the "Golden Triangle", which extends across parts of Thailand, Myanmar, Laos and Southwestern China.^[30] This region has no clear borders and the people are not assigned passports. Their statelessness deprived them of basic benefits and rights, including the liberty to leave Chiang Rai province. "To get nationality is the biggest hope for the boys", head coach Nopparat said. "In the past, these boys have problems travelling to play matches outside of Chiang Rai because of their nationless status."^[33] Following the team's rescue, Thai officials promised to provide the three boys and the coach with legal assistance in obtaining Thai citizenship, a process that could take up to six months.^[34] The four were granted Thai citizenship on 26 September 2018.^[35]

British caver Vernon Unsworth, who lives in Chiang Rai and has knowledge of the cave complex, was scheduled to make a solo venture into the cave on 24 June when he received a call about the missing boys.^[36] Unsworth advised the Thai government to request assistance from the British Cave Rescue Council (BCRC).^[36][37] On 25 June, Thai Navy SEALs divers arrived and began searching the cave.^[38] A Thai Navy SEAL said the water was so murky that even with lights they could not see where they were going underwater.^[39] After continuous rain, which further flooded the entrance, the search had to be temporarily interrupted.^[40] On 27 June, three BCRC cave divers arrived with specialist equipment including HeyPhone radios,^[41] followed by separate teams of open-water divers. On 28 June, a United States Air Force team—reportedly United States Air Force Pararescuemen^[42] from the 320th Special Tactics Squadron, the 31st Rescue Squadron, and the 353rd Special Operations Group—joined them. By 29 June, an Australian Federal Police team of Specialist Response Group divers had arrived, followed by a Chinese team of divers from the Beijing Peaceland Foundation on Sunday, 1 July.^{[37][43][44][45][46]}

Meanwhile, policemen with sniffer dogs searched the surface above for shaft openings that could provide alternative entrances to the cave system below. Drones and robots were also used in the search, but no technology existed to scan for people deep underground.^[47]

BCRC divers Richard Stanton and John Volanthen advanced through the cave complex placing diving guidelines, supported by Thailand-based Belgian cave diver Ben Reymenants^{[48][49][50][51]} and French diver Maksym Polejaka.^{[52][53][54][55][56]} The search had to be suspended due to the weather, as rainfall increased the flow of water in the cave where the divers were battling strong currents and poor visibility.^[49][57] The search resumed on 2 July after the weather improved. The twelve boys and the coach were discovered at approximately 22:00^[58] by Stanton and Volanthen, whose efforts were overseen from outside by BCRC diver Robert Harper.^[59] The boys and coach were on a narrow rock shelf about 400 metres (1,300 ft) beyond the "Pattaya Beach" chamber,^[58][60][61] named after an above-ground beach in Thailand. Volanthen had been placing guidelines in the cave to assist others in navigation when he ran out of line. He then swam to the surface and soon found the missing group, smelling them before hearing or seeing them.^[62][63] The ledge where they were found is about 4 kilometres (2.5 mi)^[64] from the cave mouth.^[65] A video of the encounter, showing the boys and their interactions with the divers, was posted on Facebook by the Thai Navy SEALs.^[66] Former Chiang Rai provincial governor Narongsak Osatanakorn [th], who was in charge of rescue work, said, "We found them safe. But the operation isn't over."^[67][68] The Thai, US, Australian and Chinese diving teams supported by the BCRC divers began transporting diving bottles into the cave system and established an air supply storage area in Chamber 3.^[49][69]

On 3 July, the trapped group was joined by three Thai Navy SEALs who supported them until the rescue. The SEALs included Thai Army doctor Lt. Col. Pak Loharachun of the 3rd Medical Battalion, who had completed the Navy SEALs course.^[70][71] Thai officials told reporters that rescuers were providing health checks and treatment and keeping the boys entertained and that none of those trapped was in serious condition. "They have been fed with easy-to-digest, high-energy food with vitamins and minerals, under the supervision of a doctor", Rear Admiral Apagorn Youkonggaew, head of the Thai Navy's Special Forces, told reporters. A video made by the rescuers, and shared a few hours later by the Thai Navy SEALs, showed all twelve boys and their coach introducing themselves and stating their age. Wrapped in emergency blankets and appearing frail, they all said hello to the outside world. "Sawatdi khrap", each boy said with his palms together in wai, the traditional Thai greeting.^[72] A second video shows a medic treating them.^[73] It was believed that some of the group could not swim,^[74] complicating what would already be a difficult rescue.^[75] The Army doctor discovered that they had attempted to dig their way out of the cave. The team members had used rock fragments to dig every day, creating a hole five metres deep.^[71]

BCRC diver Jason Mallinson offered the boys and coach an opportunity to send messages to relatives by using his wet notes pad.^[57] Many of the notes said they were safe, reassured family members that everything was fine, and included words of love, reassurance and encouragement.^[76]

A logistics camp was established at the cave entrance, which accommodated hundreds of volunteers and journalists in addition to the rescue workers. The site was divided into several zones: restricted areas for the Thai Navy SEALs, other military personnel, and civilian rescuers; an area for the relatives to give them privacy; and areas for the press and the general public.^[77]

An estimated 10,000 people contributed to the rescue effort, including more than 100 divers, representatives from about 100 government agencies, 900 police officers, 2,000 soldiers and numerous volunteers. Equipment included ten police helicopters, seven police ambulances, and more than 700 diving cylinders, of which more than 500 were in the cave at any time while another 200 were in the queue to be refilled. More than a billion litres of water (the equivalent of 400 Olympic-size swimming pools) was removed.^[78][79]

The place where the boys became stranded was about 4 kilometres (2.5 mi)^[64] from the entrance and 800–1,000 metres (2,600–3,300 ft) below the top of the mountain.^[80] The route to their location was blocked by several flooded sections, some with strong currents and zero visibility,^[81] and there were some extremely narrow parts, the smallest measuring only 38 by 72 centimetres (15 in × 28 in).^[82][83][84] The journey through the cave to reach the boys took six hours against the current and five hours to exit with the current,^[85] even for experienced divers.^[86]

The rescue workers battled rising water levels from the outset. In an effort to drain the cave, a stone diversion dam was built upstream, and systems were installed to pump water out of the cave and divert flows that were entering it. On 4 July, it was estimated that the pumps were removing 1,600,000 L/h (420,000 US gal/h) from the cave, ruining nearby farm fields in the process.^[87][88] For a time, well-meaning volunteers were inadvertently pumping water back into the groundwater supply.^[89] Helped by a spell of unseasonably dry weather, these efforts reduced water levels by 1.5 centimetres (0.6 in) per hour on 5 July, enabling the rescue teams to walk 1.5 kilometres (0.93 mi) into the cave. However, heavy rains forecast for 8 July were expected to halt or reverse the process and could even flood the position where the boys and their coach were trapped.^[90]

On 6 July, the oxygen level in the cave was detected to have dropped, raising fears that the boys might develop hypoxia if they remained there for a prolonged time. By 8 July, the oxygen level was measured to be 15%; the level needed to maintain normal function for humans is between 19.5% and 23.5%.^[91] Thai military engineers attempted to install an air supply line to the boys, but the effort was abandoned as impractical.^[57]

As the crisis unfolded, rescuers planned several different methods to save the team and coach. The principal options were to:^{[86][92][93][75]}

• Wait until the end of the monsoon season; with divers providing food and water.
• Teach the group basic diving skills.
• Find an alternative entrance to the cave which could allow for an easier escape; one shaft was discovered that went down 900 metres.^[94]
• Drill a rescue shaft; more than 100 shafts were bored into the soft limestone, but no suitable location was found.^[80][83]
• Build an air line.
• Build a telephone line to communicate.

Multiple dangers—the threat of more heavy rain, dropping oxygen levels, and the difficulty or impossibility of finding or drilling an escape passage—forced rescuers to make the decision to bring out the team and coach with experienced divers.^[57][95] The Thai Navy SEALs and US Air Force rescue experts met with the Thai Minister of the Interior who approved the plan.^[57][96] 90 divers worked in the cave system, 40 from Thailand and 50 from other countries.^[20] The media initially reported that the Thai military had said rescuers would teach the boys basic diving skills to enable them to make the journey.^[83][93][97] However this was quietly deemed too risky and instead the boys were fully sedated and were unconscious for the journey.^[98][99] Organisers built a mock-up of a tight passage with chairs, and divers practiced with local boys in a school swimming pool. Thai SEALs and US Air Force experts then refined the plan to use teams of divers to bring out the weakened boys.^[96]

On 5 July, at 8:37 pm, Saman Kunan (Thai: สมาน กุนัน; born 23 December 1980), a 37-year-old^[100] former Thai Navy SEAL, made a dive from Chamber 3 to the T-junction close to Pattaya Beach to deliver three air tanks.^[101][102] During his return dive, he lost consciousness underwater. His dive buddy attempted CPR without success. Kunan was brought to Chamber 3 where CPR was attempted again, but he could not be resuscitated and was pronounced dead at about 1 am on 6 July.^[101][103]

Formerly a member of Thai Navy SEALs class 30, Kunan had left the SEALs in 2006 at the rank of petty officer 1st class; he was working in security at Bangkok's Suvarnabhumi Airport when he volunteered to assist with the cave rescue.^[101][103] He was posthumously promoted to lieutenant commander by the Commander-in-Chief of the Royal Thai Navy, an unprecedented rise of seven ranks.^[104][105] A funeral, sponsored and attended by the Thai royal family, was held on 14 July. On the same day, Kunan was awarded the Knight Grand Cross (first class) of the Most Exalted Order of the White Elephant by King Maha Vajiralongkorn.^[105]

Another rescue diver and Thai Navy SEAL, Beirut Pakbara, died the following year from septic shock after acquiring an unspecified latent blood infection during the rescue operation.^[106][107]

On the morning of 8 July, officials instructed the media and all non-essential personnel around the cave entrance to clear the area as a rescue operation was imminent, due to the threat of monsoon rains later in the week, which were expected to flood the cave until October.

For the first part of the extraction, 18 rescue divers—13 international cave divers and five Thai Navy SEALs—were sent into the caves to retrieve the boys, with one diver to accompany each boy on the dive out.^{[57][108][109][110]} The international cave diving team was led by four British divers: John Volanthen, Richard Stanton, Jason Mallinson, and Chris Jewell (each assigned a boy), and two Australians: Richard Harris, an anesthesiologist, and his friend Craig Challen, a veterinarian.^{[51][57][111]} Irishman Jim Warny became an additional lead diver on the final day of the rescue to bring back assistant coach Ekkaphon,^[112] and physician Harris took over the lead rescue of Pong.^{[25]: 268–270} The lead divers' portion of the journey would stretch over one kilometre, going through submerged routes while being supported by 90 Thai and foreign divers at various points performing medical check-ups, resupply of air tanks, and other emergency roles.^[113]

There were conflicting reports that the boys were rescued with the weakest first or strongest first. In fact, the order was which boy volunteered first.^[16] "I talked with Dr. Harris. Everyone was strong and no one was sick," Ekkaphon told the press. "Everybody had a strong mental state. Dr. Harris said ... there's no preference." The team decided as a group that the boys who lived the farthest away should leave first. Ekkaphon also stated in their 18 July press conference, not realizing at the time that their story had attracted global media attention: "We were thinking, when we get out of the cave, we would have to ride the bicycle home ... so the persons who live the furthest away would be allowed to go out first ... so that they can go out and tell everyone that we were inside, we were okay."^[114]

Each boy was dressed in a wetsuit, with a buoyancy aid, harness, and a positive pressure full-face mask. Harris administered the anaesthetic ketamine to the boys before the journey, rendering them "fully unconscious."^[115] This was to prevent them from panicking on the journey, which would risk their lives and those of their rescuers.^[25]: 99 They were also given the anti-anxiety drug alprazolam, and the drug atropine to steady their heart rates and reduce saliva production to prevent choking.^{[25]: 129 [97][116][117]} A cylinder with 80% oxygen was clipped to their front, a handle was attached to their back, and they were each tethered to a diver in case they were lost in the poor visibility. The rescue divers described each child as "a package".^{[57][118][119][120]} The Thai government granted Harris and two medical assistants diplomatic immunity against judicial action,^{[25]: 136–138} in case something went wrong.^{[118][121][122][123]}

The anaesthetic lasted between 45 minutes and one hour, requiring divers, whom Harris had trained, to administer "top-up" ketamine injections during the three-hour journey.^{[57][99][124]} The boys were maneuvered out by the swimming divers who held onto their back or chest, with each boy on either the right or left side of the diver, depending on the guideline; in very narrow spots the divers pushed the boys from behind.^[57][119] The boys were carefully navigated through tight passages to avoid dislodging their face masks against rocks. The divers kept their heads higher than the boys so that, in poor visibility, the divers would hit their head against the rocks first.^[57] The divers knew the boys were breathing from their exhaust bubbles, which they could see and feel.^[118]

After a short dive to a dry section, the divers and boys were met by three divers, and the boys' dive gear was removed.^[116] The boys were then transported on a drag stretcher over 200 m (660 ft) of rocks and sand hills. Craig Challen assessed them, and their dive gear was put back on before they were re-submerged for the next section.^[57] The boys arrived at 45-minute intervals.^[125]

After being delivered by the divers into the staging base in Chamber 3, the boys were passed along a "daisy chain" by hundreds of rescuers stationed along the treacherous path out of the cave.^[126] Wrapped in "sked" rescue stretchers, the boys were alternately carried, slid and zip-lined along a complex arrangement of pulleys installed by rock climbers.^[127] Many areas from Chamber 3 to the entrance of the cave were still partially submerged and rescuers described having to transport the boys over slippery rocks and through muddy water for hours.^[128] The journey from Chamber 3 to the cave entrance had initially taken about four to five hours, but this was reduced to less than an hour after a week of draining and clearing the mud path using shovels.^[126]

The authorities warned that the extraction would take several days to complete because crews had to replace air tanks, gear, and other supplies, requiring ten to twenty hours between each run.^{[32][129][109]} Shortly after 19:00, local officials confirmed that two of the boys had been rescued and taken to Chiangrai Prachanukroh Hospital.^{[130][131][132]} Shortly afterwards, two more boys exited the cave and were assessed by medical officials.^[130] Low water levels had reduced the time required for the rescues.^[133] The lower water was due to improved weather and the construction of a weir outside the cave to help control the water.^[134]

On 9 July, four more boys were rescued from the cave.^[135] On 10 July, the last four boys and their coach were rescued from the cave.^{[3][4][5][111][136]} The rescue procedure was streamlined with practice, so the total time to extract a boy was reduced from three hours on the first day to just over two hours on the final day, allowing four boys and the coach to be rescued.^[110][125] The three Thai Navy SEALs and the Army doctor who had stayed with the boys the entire time were the last to dive out. Three of these divers made it to Chamber 3, joining waiting rescuers when the pumps shut off for an uncertain reason, possibly due to a burst water pipe.^[137][138] The water levels in Chamber 3 started to rise, which would have cut off their access to the first two chambers and the cave entrance.^[137] "All of a sudden a water pipe burst and the main pump stopped working," a diver stated. "We really had to run from the third chamber to the entrance because the water level was rising very quickly—like 50 cm every 10 minutes."^[138] This forced up to 100 rescuers still located more than 1.5 kilometres (0.93 mi) inside the cave to evacuate in a hurry, abandoning the rescue equipment inside the cave.^[139] The last diver made it back to Chamber 3 as everyone was preparing to leave.^[137] The rescuers managed to rush to the cave exit in under an hour.^[139]

A number of news outlets reported on the role of assistant coach Ekkaphon during the rescue. Previously a Buddhist monk, he had calmed the boys by guiding them in meditation during the ordeal. He also passed on a message in which he apologised for putting the children in danger.^[22][140]

Thai authorities reported that the rescued boys were able to eat rice porridge, but more complex foods would be withheld for ten days.^[141] The Thai Health Ministry said the boys had lost an average of 2 kilograms (4.4 lb) each, but they were in "good condition".^[142] They were placed in quarantine while health workers determined whether they had caught any infectious diseases, and they were expected to remain hospitalised for at least one week.^[143] Because of the prolonged stay in a damp cave environment, officials were worried about potential infections such as histoplasmosis or leptospirosis.^[144] Parents of the team members initially visited their children by looking through a window, but as soon as laboratory results proved negative, they were allowed to visit in person while wearing a medical gown, face mask and hair cap.^[145]

The boys wore sunglasses as a precaution while their eyes adjusted to the daylight. Detailed tests of their eyes, nutrition, mental health and blood were carried out. A Health Ministry physician said all the boys showed an increase in white blood cells, so preventive antibiotic doses were given to the entire team.^[145]

Residents of Chiang Rai province volunteered to cook, clean for, and otherwise support the missing team's families and the rescue teams at the encampment by the cave mouth.^[13] Social media was used to draw attention to the rescue attempts.^[13] Classmates and teachers of the team spent time chanting and praying for the missing boys.^[146] Classmates of one of the boys made 1,000 paper cranes for him, while praying for his safe return.^[147] Local schools donated money to help the parents with living costs, as many of them stopped working in order to follow the rescue attempts.^[77]

On 29 June, Prime Minister Prayut Chan-o-cha visited the search site and told the families of the boys not to give up hope.^[148] Following the death of Saman Kunan, King Vajiralongkorn announced that he would sponsor his funeral.^[149]

After the rescue was completed, the boys' families, the rescue commander, military officials, and thousands of volunteers gathered at the cave entrance. The group gave thanks for the lives saved and asked forgiveness from the cave goddess "Jao Mae Tham" for the intrusion of pumps, ropes and people during the rescue.^[150]

Some observers, primarily in Western media, questioned whether assistant coach Ekkaphon Kanthawong should face criminal charges for leading the group into the caves, despite the warning sign at the entrance stating that it is dangerous to enter between July and November.^[151] The boys had entered the cave on 23 June.

Local communities, as well as the boys' parents, emphasised that they did not blame the boys or their coach, as the rain had arrived a month earlier than usual.^[152] Vern Unsworth, a British caver mapping the cave, stated, "Nobody's to blame, not the coach, not the boys. They were just very unlucky ... It wasn't just the rain that day, the mountain is like a sponge and waters from earlier rain were raising the levels." Unsworth said that he himself had been planning to make a solo venture into the complex on 24 June, when he received a telephone call saying the boys were missing there.^[153]

While the police chief told newspaper Khao Sod that he "hadn't ruled out" pressing negligence charges against the coach for putting the team in danger, no calls were made to take legal action against him. A number of lawyers stated that the coach would probably not face criminal charges, since Thai law also takes into consideration whether a person has malicious intent. In mainstream media, Ekkaphon has widely been held "a hero" and was a "calm voice [that] helped boys to beat despair in the darkness."^{[154][155][156]} The coach was reported to have treated the boys with care, giving them his food, helping them remain calm, and instructing them to drink the relatively clean water dripping from the cave walls instead of the murky floodwaters that trapped them.^{[citation needed]}

When asked if Ekkaphon should be held legally responsible for negligence, Mongkhon Bunpiam, the father of 12-year-old Mongkhon, rejected the suggestion: "We would never do that ... the boys love their coach ... and we as parents don't want it either. Coach Eak has been good to my boy, and now I hear how he gave them hope, and kept them calm for so many days without food. I have great admiration for him."^[154] Tanawut Vibulrungruang, father of 11-year old Chanin, was reported to be "touched by the actions of the team's coach. Without him ... he doesn't know how the kids could have survived."^[157] Head coach Nopparat said he would not have approved of the hike, but was confident in Ekkaphon's ability to take care of the boys. Prime Minister Prayut Chan-o-cha said that the emphasis should be on the rescue and the recovery of the team, and he asked the public to avoid a rush to judgment.^{[158][159][160]}

Over the course of two weeks, hundreds of volunteers, military specialists and corporate experts arrived from around the world to offer assistance in the rescue.

•  Australia: Six Australian Federal Police (AFP) Specialist Response Group divers, one Navy Clearance diver, one Australian Medical Assistance Team (AUSMAT) member and Department of Foreign Affairs and Trade Crisis Response Team officers. Up to 20 Australians were involved at the cave site.^[161][162] Doctor Richard Harris, an anaesthetist, was part of the medical team that determined the boys' fitness to make the 4-kilometre (2.5 mi) journey. Harris and his diving partner, retired veterinarian Doctor Craig Challen, both cave diving specialists, played key roles in the rescue. The Thai government provided Harris with diplomatic immunity to protect him in case anything went wrong with the sedation.^[57][121]
•  Belgium: Ben Reymenants, the owner of a diving school in Phuket, contributed in cave diving capacity.^[163]
•  Canada: Erik Brown, a dive instructor from Vancouver, participated on the cave diving team.^[164]
•  China: A six-man team from the volunteer rescue organisation, the Beijing Peaceland Foundation, arrived on 29 June.^[46] The team brought rescue equipment including an underwater robot, diving equipment and a three-dimensional imager.^[163] A second Chinese team arrived on 30 June from the Green Boat Emergency Rescue organisation with expertise in search and rescue on mountains and in caves.^[165]
•  Czech Republic: The government of the Czech Republic offered to provide a Czech manufacturer's high-performance pumps; the state has four such pumps, each with an output of 400 litres per second (1,440,000 L/h (380,000 US gal/h)).^[166] Upon inspection at the site, however, it was determined that heavy-duty pumps could not be used because of the unsuitable terrain.^[167]

The ordeal captured the attention of media from around the world. Over a period of three weeks, articles relating to the incident dominated the top stories section at many major news publications.^[197] Following the completion of the rescue, Malaysian Prime Minister Mahathir Mohamad conveyed his congratulations, on behalf of Malaysians, to everyone involved in the brave operation to save those trapped in Chiang Rai.^[198]

On 3 July 2018, a Twitter user asked whether Elon Musk could "assist in anyway [sic] to get the 12 Thailand boys and their coach out of the cave."^[206] The following day, Musk replied: "I suspect that the Thai govt has this under control, but I'm happy to help if there is a way to do so."^[207]

By 6 July, Musk commented that engineers from SpaceX and the Boring Company were headed to Thailand to see if they could assist the government in the rescue.^[208]

On 7 July, Musk revealed that he and his team planned to build a "tiny, kid-sized submarine" made from the liquid oxygen transfer tube from a Falcon rocket. The submarine would be light enough to be carried by two divers while being robust and small enough to fit through the narrow gaps.^[209] Later that day, Musk mentioned that construction on the submarine was complete and that it was being shipped to Thailand.^[210] On 8 July, Musk shared a video of the submarine being tested in a pool through a simulated narrow passage.^[211]

Also on 7 July, Rick Stanton emailed Elon Musk stating "It is absolutely worth continuing with the development of this system in as timely a manner as feasible. If the rain holds it out it may well be used."^[212]

On 8 July, Rick Stanton again emailed Elon Musk stating that they were worried about the smallest of the children and requested that they "please keep working on the capsule".^[212]

By 9 July, Musk had arrived at the rescue site and visited Cave 3. He commented that the "mini-sub" was ready if needed and that it would be left in Thailand should it be needed for the rescue or for future events.^[213] However, the submarine was not used during the rescue. Additionally the local governor, Narongsak Osotthanakorn, stated that it was "not practical",^[214] to which Musk responded that the governor was not a subject matter expert and mentioned the previous emails by Rick Stanton.^[215] Vern Unsworth, who helped get the attention of British cave rescue divers, ridiculed the "mini-sub" as a public relations stunt and suggested in a CNN interview that Musk "stick his submarine where it hurts".^[216] In retaliation for this, Musk falsely accused Unsworth of paedophilia, and hired a private investigator in an attempt to discredit him.^[217] Musk issued a public apology to Unsworth after Unsworth unsuccessfully sued him for defamation.^[218]

• 23 June 2018 (2018-06-23): The team enters the Tham Luang cave shortly after football practice and prior to heavy rain. The mother of one of the boys later reports to local police that her son is missing after he has failed to arrive home. When rumours begin to spread about the boys going into the Tham Luang cave, the police investigate and find shoes and bicycles near the cave entrance.^[219]
• 24 June 2018 (2018-06-24): Handprints and footprints of the boys are found by officials. A vigil is held outside the cave by relatives.^[219]
• 25 June 2018 (2018-06-25): Thai Navy SEAL divers enter the cave to search for the team.^[219]
• 26 June 2018 (2018-06-26): Having arrived at a T-junction, divers are pushed back by floodwaters that have blocked an elevated air pocket near Pattaya Beach where it is believed the team may have been stranded.^[219]
• 27 June 2018 (2018-06-27): British and US military teams of divers and experts are sent to Thailand to help with the search. Divers re-enter the cave system but quickly retreat due to another flooding.^[94][219]
• 28 June 2018 (2018-06-28): Heavy rains cause the rescue operation to stop temporarily. Pumps are delivered to drain the water. Drones are dispatched to assist more than 600 people in their search for new vents in the cave roof.^[94][219]
• 29 June 2018 (2018-06-29): Thai Prime Minister Prayut Chan-o-cha visits the site.^[219]
• 30 June 2018 (2018-06-30): The search resumes after divers take advantage of a brief pause in the rainfall. They advance further but are still far from where they believe the boys to be stranded.^[219]
• 1 July 2018 (2018-07-01): As divers go deeper into the cave, they use Chamber 3 as an operating base to store diving cylinders and other supplies which are replenished by support divers transiting back and forth to the cave entrance.^[219]
• 2 July 2018 (2018-07-02): At around 8:20 pm,^[58] the boys and their coach are found alive on elevated land, 400 m (1,300 ft) further than Pattaya Beach. They are discovered by the British diving team, including Richard Stanton and John Volanthen.^[219] Communication is difficult as Adul Sam-on is the only English speaker.
• 3 July 2018 (2018-07-03): Seven Thai Navy SEAL divers deliver food, medicine and supplies to the boys, including high-calorie gels and paracetamol.^[219] Four of the divers, including Doctor Pak Loharnshoon, volunteer to stay with the boys inside the cave for a week until all 12 can be extracted.^[220] The four divers will be the last people to exit the cave after the rescue is completed.^[221]
• 4 July 2018 (2018-07-04): The team is taught how to use a full-face diving mask and breathing apparatus. Rescue teams work on continuing to pump water from the cave; at this stage, they have already pumped out over 30 million gallons.^[219]
• 5 July 2018 (2018-07-05): The rescue is forced to move more quickly because of expected rain. Another group searches the mountains for any new cracks or openings.^[219]
• 6 July 2018 (2018-07-06): Saman Kunan, a former Thai Navy SEAL diver and volunteer of the rescue mission, dies in the early hours of the morning after losing consciousness while placing diving cylinders underwater along the route to the stranded boys.^[222] Authorities urge that the rescue needs to speed up, as the oxygen levels are falling to 15%, well below the 21% "safe zone".
• 7 July 2018 (2018-07-07): The rescue chief claims that it is not suitable for the team to dive yet. More than 100 vents are being drilled in a third attempt to reach the team. However, an accident to a rescue vehicle injures six people, and the effort is called off.^{[citation needed]} A letter from the team's coach reaches the outside, apologising to the boys' parents, along with letters from the boys to their parents.^[20][219]
• 8 July 2018 (2018-07-08): An international contingent of 13 specialist divers and five Thai Navy SEALs,^[109] including four British and two Australian divers,^[111] enters the cave to begin bringing the boys to safety.^[223] Since the most difficult parts of the passage are too narrow for more than one rescuer, each boy is assigned as the responsibility of a single rescue diver. Adding to each solo rescuer's challenge is that, in order to prevent underwater panic and to eliminate body movements that would endanger the rescue, each child is put under general anesthesia just prior to being extricated.^[224] So, in addition to manipulating the boy through narrow cave sumps, the diver also has to monitor the consciousness and breathing of a medical patient.^{[25]: 165–166} The first boy is reported to have emerged from the cave at about 5:40 pm, and the fourth at about 7:50 pm,^[134] though not all sources agree. The four boys are taken to Chiang Rai Prachanukroh, a local hospital. It is announced that divers will not resume the rescue for at least another 10 hours, as they need to replenish supplies.^[219]
• 9 July 2018 (2018-07-09): Four more boys are confirmed to have been extracted from the cave and transported to the hospital. It is announced that the boys will be kept in quarantine.^[225]
• 10 July 2018 (2018-07-10): The remaining four boys and their coach are rescued.^{[3][4][5][226]} It is later confirmed that all of the rescue divers have also successfully exited the cave.^[226][227]
• December 2019 (2019-12): Thai Navy SEAL Beirut Pakbara dies from a blood infection contracted during the cave rescue.^[228]

When the rescue operation was concluded, the Tham Luang Nang Non cave and adjacent forest park were immediately closed to the public.^[230] Realising the massive tourism potential, the Thai authorities announced plans to turn the cave into a living museum to showcase the multinational rescue effort.^[231] The head of the rescue mission and former governor of Chiang Rai province, Narongsak Osatanakorn [th], predicted that the area was set to become a "major attraction for Thailand",^[231] and the deputy head of national parks, Chongklai Woraponsathron, said "we are lucky that we are going to have a world class tourist attraction".^[232] However, Prime Minister Prayut Chan-o-cha highlighted the concerns for tourist safety and stated that the cave was "dangerous",^[232] insisting that the site could not be reopened until adequate precautions had been implemented to safeguard visitors.^[230] Prior to the 2018 cave rescue, the area was largely undeveloped and had limited facilities for tourists.^[231]

To honour those involved in the rescue operation, a huge mural was created by a team of local artists.^[233] It first went on display at Wat Rong Khun, a Buddhist temple in Chiang Rai province, before being moved to a memorial pavilion near the Tham Luang cave entrance in December 2018.^[234] Saman Kunan, the former Thai Navy SEAL who died during the rescue operation, is commemorated with a twice life-size bronze statue situated in front of the memorial pavilion.^[235] Designed by renowned national artist Chalermchai Kositpipat^[236] and produced at a fine art foundry in Thailand's Ayutthaya province, the statue depicts Kunan with 13 wild boars at his feet, symbolising the 12 boys and their football coach.^[237]

After the forest park was reopened on 16 November 2018, thousands of tourists flocked to the site, but they were not allowed inside the cave as work was under way on creating a living museum dedicated to the rescue.^[238] The cave was officially opened to the public 12 months later, on 1 November 2019, in an inauguration ceremony attended by monks, Thai government officials and forest rangers.^[239] This was the first time since the rescue that tourists had been allowed to enter the cave itself,^[240] although there was a limit of twenty people at a time, and they were only permitted to visit the main entrance cavern.^[241] At around the same time, Tham Luang was upgraded from a forest park to a national park in view of its enhanced status as a tourist hotspot.^[241] Forestry officials said that prior to the rescue, around 40,000 tourists had visited the area each year, but more than 1 million had visited since the park reopened the previous November.^[240]

On 24 June 2023, a ceremony was held in front of the Tham Luang cave to mark the fifth anniversary of the search and rescue mission.^[242] The cave system was then reopened in phases for public access and adventure tourism.^[243] The first two chambers were opened to the public in July 2023, with large groups guided as far as Chamber 1 multiple times a day, while smaller groups could visit Chamber 2 on pre-booked guided tours.^[244] Limited tours to the third chamber, which served as the hub of the rescue operation, began in December 2023.^[245][246] Accompanied by licensed tour guides, small numbers of tourists can experience the obstacles encountered by the rescue teams and understand the extremely complicated rescue work that was carried out in July 2018.^[246] The equipment used by the divers, including ropes, cables and oxygen tubes, remains untouched as exhibits for the visitors to view for themselves.^[247] The area after Chamber 3 remains closed to the public, but there are plans to open it up further in the future for more experienced cavers to explore.^[247] Back at the cave entrance, display boards give details of the rescue operation, and some of the bicycles are still standing where the boys left them on the day they entered the cave.^[246]

Following the incident, cave-diving was incorporated into the training regime for Thailand's Navy SEALs to better prepare them for similar emergencies.^[248] As three of the boys and their assistant coach were stateless, officials promised that the four would be granted Thai citizenship within six months,^[34] and this happened on 26 September 2018.^[35] The Thai government vowed to end statelessness by 2024.^[249]
