Crashed in unknown circumstances ten miles of Marysville while completing a test flight out from McClellan AFB. All six crew members were killed.

The crew was engaged in a sortie from Mather AFB, Sacramento. En route, the failure of the cabin pressurization system caused by a window crack forced the crew to make an emergency descent. The pilot informed ground about his situation and elected to divert to the nearest airport when all crew members decided to abandon the airplane that crashed in an uninhabited area located 15 miles west of Yuba City. The airplane was totally destroyed and all eight crew members were rescued, four of them were injured.

The crew was completing a transpacific flight from Wake Island to Biggs AAF. While descending by night under VFR mode, the pilot informed ground his fuel reserve was low. On approach, the airplane struck the ground in a desert area, slid for 300 yards and eventually crashed on a sand dune and exploded six miles from runway 21 threshold. The aircraft was destroyed and all nine crew members were killed.

The crew departed Selfridge AFB on a refuelling mission, carrying a load of 9,500 gallons of fuel. Shortly after takeoff, while in initial climb, one of the engine failed. The aircraft lost height, stalled and crashed in a huge explosion few km from the airfield. On impact, few debris scattered around and struck several houses and a mill. The aircraft disintegrated and all five crew members were killed. There were no injuries on the ground.

While approaching Argentia-Bristol Field by night, the four engine aircraft crashed into the Trinity Bay about 50 km northeast of Argentia. In the early morning, few debris were found floating on water and all 23 occupants have been killed.

A fuel leak occurred in the right wing while cruising at high altitude. The crew decided to divert to Seymour Johnson AFB for a safe landing but on final, the right wing detached. The airplane crashed in a huge explosion in a field located 12 miles from the runway threshold. Three crew members were killed while five others were injured. The aircraft was carrying two Mark 39 thermonuclear bombs that were later recovered. In 2013, documents and information relating this story were declassified by the US Government.

After touchdown at Bilbao-Sondica Airport, the four engine airplane encountered difficulties. Unable to stop within the remaining distance, it overran, lost its undercarriage and came to rest few dozen yards farther. There were no injuries among the occupants while the aircraft was written off.

The crew departed Biggs AAF at 1715LT on a training flight. While overflying Utah at an altitude of 40,000 feet, the airplane encountered severe turbulences that affected its structure. In such conditions, all seven crew members decided to abandon the aircraft and bailed out. Out of control, the B-52 dove into the ground and crashed in a field located near Monticello, Utah. A crew member was killed while six others were rescued.
