The 1964 T-39 shootdown incident occurred on 28 January 1964, when an unarmed United States Air Force T-39 Sabreliner on a training mission was shot down over Erfurt, East Germany by a Soviet Mikoyan-Gurevich MiG-19 fighter aircraft. The occupants of the aircraft were Lieutenant Colonel Gerald K. Hannaford, Captain Donald Grant Millard and Captain John F. Lorraine. All three died, becoming some of the few direct casualties of the Cold War.
