*10 January – The [[Dassault Balzac V]] crashes on its 125th sortie, during a low-altitude hover. During a vertical descent the aircraft experienced uncontrollable divergent wing oscillations, the port wing eventually striking the ground at an acute angle with the aircraft rolling over because of the continued lift engine thrust. The loss was attributed to loss of control because the stabilising limits of the three-axis autostabilisation system's 'puffer pipes' were exceeded in roll. Although airframe damage was relatively light, the ''Centre D'Essai en Vol'' test pilot, Jacques Pinier, did not eject and died in the crash.<ref>Jackson, Robert, "Combat Aircraft Prototypes since 1945", Arco/Prentice Hall Press, New York, New York, 1986, Library of Congress card number 85-18725, ISBN 0-671-61953-5, page 147.</ref>

*13 January – [[United States Air Force]] [[B-52 Stratofortress|B-52D-10-BW Stratofortress]], ''55-060'', suffers structural failure in turbulence of winter storm, crashes approximately 17 miles SW of [[Cumberland, Maryland]]. Pilot, co-pilot, eject, survive. Navigator, tail gunner, eject, die of exposure. Radar nav fails to eject, rides airframe in with two nuclear weapons on board. Both bombs survive intact and are recovered.<ref name="Gibson" />

*February - During an airpower demonstration, an [[B-26 Invader]] on a strafing pass over a range at [[Eglin AFB]], Florida, loses a wing as it pulls up, with the loss of both crew. The USAF subsequently grounds all combat B-26s as the stress of operations now exceed the airframes' abilities. [[On Mark Engineering Company]] remanufactures 41 old airframes as one YB-26K and forty B-26Ks with new spars, larger engines and rudders, and new 1964 fiscal year serial numbers which see use in Southeast Asia, and which will be redesignated A-26As for political reasons. <ref>Thompson, Scott, "Douglas A-26 and B-26 Invader", The Crowood Press Limited, Ramsgate, Marlborough, Wiltshire, UK, 2002, ISBN 1-86126-503-4, pages 138-141.</ref>

*Post-April - Third prototype [[SAAB]] [[J 29 Lansen]], ''32-3'', first flown April 1954 and tasked with armament testing, crashes after just 35 flight hours when it flies into the ground at high speed, killing Bengt Fryklund, an experienced pilot who had graduated at the top of his intake at the [[Empire Test Pilot School]]. Cause was difficult to determine as airframe was destroyed. <ref>Lindholm, Robin, and Stridsberg, Sven, "''Nordic Lance - SAAB's Fantastic Lansen''", Air Enthusiast, Stamford, Lincs, UK, Number 125, September-October 2006, page 29.</ref>
*1 April - In an unusual accident, the Number Three deck elevator of the [[USS Randolph (CVS-15)]] tears loose from the ship during night operations and plunges into the Atlantic, taking with it an [[S-2 Tracker|S-2D Tracker]], five crewman, and a tractor. Three crew are rescued by the [[USS Holder (DD-819)]], but two are lost at sea. <ref>Pawlowski, Gareth L., "''Flat-Tops and Fledglings: A History of American Aircraft Carriers''", Castle Books, New York, 1971, Library of Congress card number 76-112765, page 140.</ref>

*9 May – A [[Republic]] [[F-105B Thunderchief|F-105B-15-RE Thunderchief]], ''57-5801'', Thunderbird 2, delivered to the [[Thunderbirds]] demonstration team in April 1964, suffers structural failure and disintegrates during 6G tactical pitch up for landing at airshow at [[Hamilton AFB]], California, killing pilot Capt. Eugene J. Devlin. The failure of the fuselage's upper spine causes the USAF to ground all F-105s and retrofit the fleet with a structural brace, but the air demonstration team reverts to the [[F-100 Super Sabre]] and never flies another show in F-105s.<ref>http://home.att.net/~jbaugher/1957.html</ref><ref>Thompson, Warren E., "''F-105 Thunderchief''", Combat Aircraft, Ian Allen Publishing, Hersham, Surrey, UK, February-March 2009, Volume 10, Number 1, page 68.</ref>
