Circumstances:
While flying over Nebraska by night at an altitude of 23,000 feet on a flight from Travis AFB to Harrisburg, PA, the aircraft suffered an explosion. It entered a dive and crashed in flames in a field located 5 miles northeast of Palisade. The aircraft disintegrated on impact and all five crew members were killed.
Crew:
Maj Harold W. Tabor, pilot,
1st Lt Duane D. Burdette, copilot,
S/Sgt Ira E. Bowers, loadmaster,
M/Sgt Joseph P. Tierney, flight engineer,
T/Sgt James J. Clouse, flight engineer.
Probable cause:
It was determined that the explosion of the airplane was the consequence of the presence of a 11 inches crack located above the left side door that broke away in flight, causing an explosive decompression of the cabin. In such conditions, the crew was unable to maintain control of the airplane.

Circumstances:
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.
Probable cause:
Failure of the propeller control and propeller power circuit on approach, causing the engine to flameout.

Circumstances:
The ill-fated aircraft that crashed was a Douglas C-133A Cargomaster s/n 56-2014 from Military Air Transport Service’s 1st Air Transport Squadron, based at Dover Air Force Base in Delaware. It arrived at Goose Bay 01:55 hours local time. After a 15-hour crew rest, they proceeded to depart enroute to Thule Air Base, Greenland with a stop enroute at Sondrestrom Air Base, also in Greenland. They were loaded with meat and other provisions. The first departure attempt was delayed due to a technical issue. The aircraft sat for a period of time without being de-iced before making a second try. At between 120 and 150 feet, the aircraft’s starboard (right) wing suddenly dropped 20 to 30 degrees. The aircraft commander managed to momentarily regain a level attitude. The aircraft then rolled to the left. The port wing dropped even more quickly and was almost vertical. The aircraft commander was unable to do anything. At 16:49 hrs local time, the Cargomaster struck the ground in a left wing down, nose high attitude.
Crew:
1st Lieutenant Guy L. Vassalotti, pilot,
Cpt Charles L. Jenkins, copilot,
Maj Frank X. Hearty, copilot,
1st Lt Douglas H. Brookfield, navigator,
T/Sgt John. A. Kitchens, flight engineer,
T/Sgt Norman H. Baron, flight engineer,
A1c Shelton Toler, loadmaster.
Probable cause:
After an intensive investigation, the accident investigation board determined the primary cause was a power stall. The most probable reason was structural icing of the wing and /or vortex generators that had accumulated ice over the 15-hour layover.

Circumstances:
About 57 minutes after his departure from Dover AFB, en route to Lajes, Azores Islands, the crew informed ground about his position flying at an altitude of 14,000 feet. In unknown circumstances, the airplane went out of control and crashed into the ocean about 1,440 km east of the coast of New Jersey. SAR operations were initiated but eventually suspended few days later as no trace of the aircraft nor the 10 crew members was found.
Probable cause:
Due to lack of evidences, the exact cause of the accident could not be determined with certainty.

Circumstances:
32 minutes after its departure from Dover AFB, while cruising east of Maryland coast at an altitude of 17,000 feet, the airplane disappeared from radar screens and crashed into the Atlantic Ocean. An empty life raft and a nose wheel were found floating on water some 53 miles east of Ocean City, Maryland, but no trace of the ten occupants was found. Amazingly, no other debris were found as the airplane was carrying 25 tons of various materials consisting of clothes, boxes and bags.
Probable cause:
Due to lack of evidences, it was not possible to determine the exact cause of the accident.

Circumstances:
Thirty-three minutes after its departure from Tachikawa AFB, the airplane crashed into the Pacific Ocean off the Japanese coasts. Few debris were found floating on water and all eight crew members were killed.
Probable cause:
The cause was determined to be structural damage resulting from a number three engine nose case failure with aircraft components striking number four engine and causing it to separate from the aircraft. Subsequent severe structural damage to wing and fuselage probably caused loss of aircraft control and electrical power.
