United States Air Force - USAF (since 1947)

Upon landing at Cape Newenham Airport, the four engine airplane went out of control and veered off runway. It went down an embankment, lost its tail and came to rest. There were no casualties.

Shortly after takeoff from Sóc Trăng, while climbing to a height of 500 feet, the airplane was hit by small arms, went out of control and crashed in a field. Seven crew members and 23 passengers (US and South-Vietnamese soldiers) were killed. Fourteen other occupants were injured.
Crew killed were:
Maj Jerry Duane Vance,
Cpt Terry Kohler,
Maj James Wesley Fulk,
Cpt Merrill Howard Masin,
Cpt Charles Price Roberts,
Cpt Timmie Joe Ward,
M/Sgt Ray Edwin Tannehill.

The heavy bomber aircraft departed Ubon Ratchathani Airport on a mission over Laos and Vietnam. Few minutes after takeoff, while cruising in stormy weather, the airplane was hit by lightning. Several instruments went out of service and shortly later, the left wing caught fire. The airplane went out of control and entered a dive during which a crew member was able to eject safely. He was later recovered and evacuated. Unfortunately, all five other occupants were killed.

The crew was engaged in a military mission to Vietnam and departed Andersen Air Base in Guam by night. While climbing in poor weather conditions, the airplane became unstable. The pilot-in-command elected to stabilize the airplane making a level off but eventually, the crew decided to abandon the aircraft and bailed out. Out of control, the aircraft crashed into the sea and was destroyed. Few hours later, five crew members were found and evacuated. Unfortunately, a six occupant (Lt Col James Lloyd Vaughan) was missing. His dead body was found 42 days later on a beach on Yap Island.

The airplane departed Ubon Ratchathani Air Base in Thailand on a night armed reconnaissance mission to attack elite NVA forces known to be infiltrating from Laos into South Vietnam along the Ho Chi Minh Trail. While making a second low pass over the target area, the airplane's n°3 engine was hit by a Strela SA-7 missile. The airplane went out of control and crashed in flames in the A Shau Valley. 12 crew members were killed while three others were rescued.

The crew was engaged in a supply mission from Thule Airbase to Dye 3 Airstrip located about 320 km east of Sondreströmfjord, Greenland. On final approach, the airplane lost height and struck the ground. On impact, the landing gear, skis, outboard fuel tanks, and the number one engine were torn off as well as 12 feet from the left wing tip and six feet of the right wing tip. The airplane came to rest in flames in the snow. Seven occupants were slightly injured while the eighth one, a Danish citizen, was killed when a propeller blade detached and penetrated the fuselage.

The crew departed Taipei-Songshan on a maritime patrol flight over the China Sea. En route, in unknown circumstances, the airplane went out of control and crashed into the sea off the Magong AFB located in the south part of the Penghu Islands (Pescadores Islands). The aircraft sank and was lost and all six crew members were killed.

Shortly after takeoff from Kon Tum, while in initial climb, the airplane was hit by a 122 mm rocket and crashed in flames in a field. A crew member survived while four others were killed.

The crew was engaged in a series of test flights on this brand new aircraft that should be delivered to the Royal Thai Air Force. Shortly after takeoff, while climbing, the engine failed. The airplane lost height and crashed. Both occupants were injured and the airplane was destroyed.

While in a low level rout one of the engines on the left side of the aircraft malfunctioned and became uncontrollable and was shut down. Hours later on final approach to Griffiss, in a driving rainstorm at night, the copilot, following the checklist turned on the starter switches for all the engines including the one that had been shut down. The shutdown engine that was now wind milling somewhere in the descent reignited and started to increase to max power. The pilots were unaware of this. As the aircraft flared out over the runway with the engine heading toward max power and the landing gear barely touching the ground the aircraft was unable to slow down to engage the brakes. The drag shut was released but failed to deploy. Unable to stop the pilot elected to go-around and increased power…but then made the decision there was not enough runways remaining and cut back the power and announced to the crew that they were going of off the end of the runway. The impact resulted in the aircraft breaking in half just behind the crew compartment and skidding down the embankment with the outboard run-away engine still running as the gear, and AGM 28 Missiles were sheared off. The Boeing reprehensive stated that most likely the only reason the aircraft did not explode on impact was due to the mud caused by the heavy rain. All crew members survived.
