While cruising by night, the crew informed ATC about technical issues with the number three and elected to feather the propeller. In the mean time, the captain decided to divert to Hickam Field. Thirteen minutes later, the crew reported he was unable to feather the propeller that was windmilling while the engine number three was losing oil. In such condition, the captain decided to divert to Johnston atoll closer from his position. Unfortunately, shortly later, a propeller detached from the engine number three and struck the ailerons, causing serious control difficulties. The crew reduced his altitude and attempted to ditch the airplane about 200 miles northeast of the Johnston atoll. Rescuers arrived twelve hours later and were able to evacuate three wounded crew members while the aircraft sank and six other occupants were killed.

The aircraft was conducting a special flight from Westover AFB to RAF Brize Norton, near London, carrying a crew of seven and eight american journalists who covered the first transatlantic flight on a KC-135 airplane. Two other similar aircraft left the airbase earlier and 56-3599 was the third of a series of four. At liftoff from runway 23, the airplane encountered serious difficulties to gain height and struck trees with its right wing. It then struck power cables and crashed in a huge explosion on the Massachusetts highway about 1,000 yards past the runway end. The aircraft disintegrated on impact and all 15 occupants have been killed.

En route to Mendoza, weather conditions deteriorated and the captain decided to attempt an emergency landing. The airplane crash landed in a field located about 20 km southeast of San Luis. The captain was injured while four other occupants were unhurt. The aircraft was damaged beyond repair.

The crew was performing a flight from Nicosia to Tehran, carrying a load of highly sensitive equipment for the CIA. Maybe following a navigational error, the four engine aircraft penetrated the Soviet Airspace over Armenia and was later attacked by the pilots of two Soviet MiG-17. The pilot of the C-118 was able to attempt an emergency landing in a field located somewhere in Azerbaijan (the exact place remains unclear). While the airplane was damaged beyond repair, all nine crew members were evacuated.

Crashed in unknown circumstances in a wooded area located 32 km northwest of Andapa. The wreckage was found two weeks later, on June 15. All four crew members were killed.

En route from Ontario (California) to Moffett AFB, the crew decided to perform five consecutive stalls. Doing so, the airplane lost 3,000 feet and suffered severe vibrations that caused structural damages to skin, stringers and bulkheads in the aft portions of the fuselage. The pilot requested permission to divert to Taft Airport for an emergency landing but shortly later, the airplane disintegrated in the air and crashed in a mountainous area located 7 miles east of Taft. The aircraft was totally destroyed and all five crew members were killed.

En route from Wheelus AFB (Tripoli) to RAF Alconbury, Cambridgeshire, the airplane suffered a double engine failure, forcing the crew to divert to RAF Krendi for an emergency landing. The airplane belly landed and came to rest on runway. There were no injuries but the aircraft was damaged beyond repair.

The twin engine aircraft departed Palanquero Airport at 0730LT. While approaching Madrid AFB near Bogotá, the airplane crashed in unknown circumstances, killing all three crew members.

En route to RAF Ouston on a flight from RAF Turnhouse, the crew was forced to attempt an emergency landing following a fuel exhaustion. The airplane crash landed in Stagshaw Bank, about two miles north of Corbridge. Both crew members were uninjured while the aircraft was damaged beyond repair.

En route from Sheppard AFB to Carswell AFB, while cruising at an altitude of 6,000 feet in poor weather conditions, the aircraft collided with a USAF Douglas C-124 Globemaster II. Registered 52-0981, the C-124 was en route from Kelly AFB to Tinker AFB with 15 people on board. Following the collision, both aircraft dove into the ground and crashed in a field located near Bridgeport. All 18 occupants on both aircraft were killed.
