United States Air Force - USAF (since 1947)

Shortly after takeoff from Ellsworth AFB, while in initial climb, the aircraft went out of control and crashed in a huge explosion in a prairie located 5 miles north of the airfield. All 17 occupants were killed.

After touchdown on runway 27R at Tempelhof Airport, the aircraft was unable to stop within the remaining distance, overran, hit a wooded fence and came to rest in flames. All four crew members were unhurt while the aircraft was partially destroyed by fire. The crew was taking part to the Berlin Airlift.

Shortly after a night takeoff from Roswell Airport, while in initial climb, the aircraft went out of control and crashed in a huge explosion six miles south of the airfield. Eight crew members were injured while 13 others were killed. It was reported that the aircraft may have been overloaded.
Crew killed were:
Maj Joe O. Will Jr., pilot,
Cpt Richard W. Hunsicker,

After takeoff, while climbing in thunderstorm activity, the aircraft went out of control and crashed in to the sea. All six crew members were killed.

On final approach to Berlin-Tempelhof Airport, taking part to the Berlin Airlift, the twin engine aircraft hit the roof of a building and crashed in flames in the adjacent street located in the suburb of Friedenau. Both crewmen were killed while three people on the ground were injured. The aircraft was destroyed by impact forces and a post crash fire.

This version was an electronic reconnaissance aircraft used in Arctic conditions. It crashed into Lake Mead, during a research flight. The crew of five was able to scramble away before the plane sank. It has been located by sonar in 170 feet of water, largely intact except for 3 missing engines (number two, three and four). The flight was for a secret missile guidance system that allowed navigation by tracking of the Sun. A low pass over calm water with pilot error put it into the lake. The aircraft plummeted from high altitude down to as close to the lake as possible. Unfortunately, Captain Robert M. Madison lost his depth perception and plowed the huge plane into the lake at 230 mph. The impact tore off all but one of the engines and sent the plane skipping along the lake surface. When she eventually stopped, she began to take on water and started to sink. Fortunately, all of the crew was able to escape into life rafts and wait for rescue.

Shortly after takeoff from Smoky Hill AFB (Schilling AFB), while on a local training flight, an engine failed. Four crew members were able to bail out before the aircraft dove into the ground and crashed in a field located two miles southeast of Smolan, about four miles south of the airbase. The aircraft was destroyed by impact forces and nine crew members were killed. Of the four crew members who were able to bail out, three were injured and one was killed.

Few minutes after takeoff from Wiesbaden-Erbenheim AFB, while climbing by night, the aircraft hit the slope of Mt Steinkopf located near Königstein im Taunus, about 16 km northeast of Wiesbaden Airport. All three crew members were killed. They were involved in the Berlin Airlift.

Crashed 2 miles southwest of Offutt AFB following an engine failure. The crew fate remains unknown.

During a night approach to Greenville, the aircraft crashed in flames and burned. At least one crew member was killed in the accident.
