United States Air Force - USAF (since 1947)

The aircraft christened 'Ciudad Juarez' departed Biggs AAF on a training mission with two F-100A Super Sabre. After five simulated missile passes followed by tail-chase gun "attacks" van Scyoc, the 188th's Safety Officer, hauled his fighter round for a final Sidewinder practice. He was closing with the bomber when his No. 2 AIM-9B suddenly left its rail, homed on to the B-52's left inboard engine pod and exploded, severing the wing. The B52 went out of control and entered a dive. Three crew members were able to bail out before the airplane crashed on Mt Taylor and was destroyed, killing five other crew members.

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.

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.
