United States Air Force - USAF (since 1947)

The crew departed Andersen AFB, Guam, on a bombing mission over the A Shau Valley. While overflying the region of Vinh, the electrical system failed, causing some of the hydraulic systems to fail as well. The captain decided to divert to Đà Nẵng Airport for an emergency landing. As the crew was unable to deploy the flaps, the captain attempted a go-around. Few minutes later, he completed a flapless landing on runway 17L. The B-52 touched down 1,000 feet past the runway threshold. After a course of 6,000 feet, it overran at a speed of 100 knots, struck a drainage ditch and came to rest in a landmine and exploded. The gunner was rescued while all five other crew members were killed in the crash.

A Boeing B-52D-75-BO Stratofortress registered 56-0595 and carrying a crew of six and a Boeing B-52D-80-BO Stratofortress registered 56-0627 carrying a crew of seven departed Andersen AFB, Guam, on a bombing mission over the A Shau Valley. While approaching the coast of South Vietnam, both aircraft collided and crashed into the mouth of the Mekong River, about 100 km south of Saigon. Three crew members on board the first aircraft were found alive as well as three others on board the second aircraft. It is believed the collision occurred when one of the crew wanted to modify his position in the formation.

On final approach to Whiteman AFB, the pilot-in-command decided to make a go-around for undetermined reason when the airplane stalled and crashed short of runway threshold. There were no casualties but the aircraft was written off.

After touchdown at Pope AFB, the airplane went out of control and veered off runway. A wing was torn off and the Hercules came to rest. All five crew members were uninjured.

The Hercules started its takeoff roll for the next leg to Quy Nhơn. Just before the aircraft was about to lift off it suddenly veered to the left and departed the runway. The pilot steered the aircraft back onto the runway but it overshot the end, rand own an embankment and burst into flames. Of the 56 passengers and crew on board a total of 35 were killed, cinlduing US, South Vietnamese and South Korean troops.

En route, the crew encountered an unexpected situation and was forced to attempt an emergency landing. The four engine aircraft crash landed in a field located 2 km southeast of Samsun Airport and came to rest in flames. While all six crew members escaped uninjured, the aircraft was partially destroyed by fire.

Few minutes after takeoff from Kadena AFB in Okinawa, while climbing to an altitude of 12,450 feet, the engine number four began to malfunction and was shut down by the crew who also feathered the propeller. The crew was cleared to return to Kadena for an emergency landing. On final approach, while at an altitude of 2,500 feet, the three remaining engines failed simultaneously. The captain decided to ditch the airplane into the sea, about 5 km offshore. The airplane broke in two and partially sank while all nine crew members were rescued.
