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.

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.

Crashed shortly after takeoff from Elmendorf AFB, killing all nine crew members.

The crew left Ladd Army Airfield in the day for a 15 hours training sortie. While flying over the Seward Peninsula at low height, the four engine aircraft christened 'The Clobbered Turkey' hit the slope of Mt Hot Springs. The aircraft was written off but all eight crew members survived. Two of them decided to walk away to find help but were found dead few days later. Six other occupants were rescued later and three rescuers were killed as well during the salvage operations.

Crashed in a mountainous area located some 30 miles northeast of Spokane. Five crew members were killed and five others were injured.

The flight had originated the previous morning when the plane took off from Davis-Monthan Air Force Base in Tucson, Arizona, for a navigational training mission to the east coast. The plane was scheduled to land at Andrews Field (Later known as Andrews Air Force Base) in Washington, D.C., but due to bad weather was diverted to Pittsburgh Airport where it arrived at 1507LT. After refueling, the aircraft proceeded towards Hanscom Air Force Base in Bedford, Massachusetts, where it was to remain overnight before flying back to Arizona the following day. However, the weather grew worse, and with poor visibility and darkness falling the crew became lost, ending up over Vermont instead of Massachusetts. Shortly after midnight on June 15, the bomber crashed into the southeast side of Hawks Mountain and exploded. All twelve men aboard were killed, and to this day the incident remains the worst aviation accident to ever occur in Vermont.
