United States Air Force - USAF (since 1947)

For unknown reasons, the four engine aircraft landed hard and bounced. It became airborne again and went out of control before crashing onto a hill. All four crew members were killed.

The four engine aircraft departed Kirtland AFB on a test flight. While cruising at low altitude, the aircraft encountered turbulences and suffered a wing failure. It crashed in a hilly terrain located some 15,5 miles north of Magdalena. All 11 crew members were killed.

The crew was dispatched at Beale AFB to follow a training program. Following several touch-and-go maneuvers, the crew started a new approach when the aircraft became unstable on final. The instructor allowed the pilot-in-command to continue the approach when the engine n°1 struck the runway surface, caught fire and exploded. Out of control, the airplane banked left and crashed, bursting into flames. All seven crew members were killed.

After landing at Wilkes-Barre Airport, the twin engine airplane was unable to stop within the remaining distance. It overran and went down a 125 feet embankment before coming to rest in flames. All five occupants were killed.

The four engine aircraft was completing a training mission from Dyess AFB (Abilene) to the Gray AAF near Killeen, carrying eight crew members. En route, while flying at low height and dropping sand bags, the airplane went out of control and crashed near Fort Hood. All eight crew members were killed.

The crew departed Eielson AFB southeast of Fairbanks on a training mission in the region of Valdez under callsign Mary 24. Following two successful approaches under MLS procedure, the crew started a third approach about four miles north of the prescribed MLS inbound course. While descending too low in poor visibility, the aircraft struck the slope of a mountain and crashed. SAR operations were initiated but eventually abandoned few days later as no trace of the aircraft nor the three occupants was found. The wreckage was recovered by walkers on August 2, 1985.

Following an uneventful flight from Howard Airbase in Panama, the crew started the approach to Trujillo Airport in marginal weather conditions. While completing a left turn at low height with gear and flaps retracted, the aircraft struck the water surface with its left wingtip. Out of control, it crashed in the sea about 13 km from the airport. All 21 occupants were killed. At the time of the accident, the visibility was estimated to be 2,500 meters in haze with a 1,500 feet ceiling and a northerly wind gusting to 25 knots.

The crew was engaged in a local training flight at Giebelstadt AFB. For unknown reasons, the four engine aircraft landed hard, causing the undercarriage and both right engines n°3 and 4 to be torn off upon landing. The aircraft slid on its belly and came to rest in flames. All four crew members escaped uninjured while the aircraft was damaged beyond repair.

The crew departed Fairchild AFB, WA, on a training mission. While cruising by night, the crew encountered an unexpected situation (unknown technical problems) and decided to abandon the aircraft that crashed in a canyon located in Hunts Mesa, about 13 miles northeast of Kayenta, AZ. Two crew members were killed while five others were rescued. The aircraft disintegrated on impact.

Shortly after takeoff, while in initial climb, the engine n°3 exploded. Debris from the engine and the nacelle hit the engine n°4 and penetrated the fuselage as well. The engine n°4 lost power and the aircraft stalled and crashed in a huge explosion, killing all nine occupants. The aircraft was en route to the island of Diego Garcia via Nairobi, carrying a load of paint.
