1964
- May 9 – (Hamilton AFB, California) – United States Air Force Capt. Eugene J. Devlin was killed when a Republic F-105B Thunderchief, 57-5801, Thunderbird 2, delivered to the US Air Force Thunderbirds demonstration team in April 1964, suffered structural failure and disintegrated during 6G tactical pitch-up for landing after an air display. The failure of the fuselage's upper spine caused the USAF to ground all F-105s and retrofit the fleet with a structural brace, but the air demonstration team reverted to the F-100 Super Sabre and never flew another show in F-105s.
- May 3 – Armed Forces Day exhibition (Bremerhaven, Germany) – Major Thomas Eugene Perfili, an American flight instructor attached to the West German Air Force, was killed in the crash of his Starfighter after losing power while demonstrating rolls.
