United States Air Force - USAF (since 1947)

The four engine aircraft was performing a flight from Charleston to Dhahran, carrying high ranking officers from the US, Pakistan and Iranian Army. The approach to Dhahran was completed by night and marginal weather conditions. Just past midnight, the aircraft struck the ground and crashed one km short of runway. Twelve occupants were killed while 26 others were injured. The aircraft was destroyed. At the time of the accident, there were scattered clouds with limited visibility. Six minutes prior to the accident, the visibility was estimated to three km with a northwest wind at 5 knots.

Nineteen minutes after his departure from Elmendorf AFB, while cruising at an altitude of 4,200 feet, the crew contacted ATC when the airplane struck Mt Bald located about 11 miles east of Talkeetna. As the airplane was fully loaded with fuel, a huge explosion occurred on impact. The aircraft was destroyed and all eight crew members were killed.
Crew (508th Air Refueling Squadron):
1st Lt Thomas H. Patton, pilot,
2nd Lt James D. Dellinger, copilot,

While cruising in marginal weather conditions from RAF Sculthorpe to RAF Burtonwood, the single engine aircraft struck a hill located near Glossop and was destroyed upon impact. Both occupants were killed.
Crew:
1st Lt John Rossman Tinklepaugh.
Passenger:
1st Lt Guy B. Waller.

Soon after a night takeoff from Castle AFB, while climbing to a height of 500 feet, the aircraft adopted a 5° nose down attitude. The crew elected to correct this but the aircraft went into a descent and struck the ground 4 miles north of the airbase and exploded on impact, killing all 10 crew members.
Crew:
Cpt John A. Goddard, aircraft commander,
Cpt Richard M. Wikstrom, pilot,
Cpt Leland Fulton Burch, navigator,
Maj Robert Louis Sherman, ECM operator
Cpt Jack Eugene Welch, radar-bombardier,
Maj Bryant Guernsey Gay, electronic counter measure operator,
T/Sgt William J. Maguire, radio operator,
Cpt Nick Sam Koss, radar-bombardier instructor,
Cpt Charles Warren Schweer, ECM instructor,
T/Sgt Gerald Everett Riley, tail gunner.

On touchdown, the nose gear collapsed and the airplane came to halt on its nose. There were no casualties but the aircraft was considered as damaged beyond repair.

Went out of control and crashed in unknown circumstances into the Potomac River off Potomac Heights, Maryland. A crew member was rescued while both other occupants were killed.

Shortly after takeoff from Lowry AFB, while climbing, the aircraft suffered a loss of power on all engines. The captain decided to divert to the nearest Airport, Denver-Stapleton. On final, the airplane stalled and crashed in flames one mile short of runway 17 threshold. All 21 occupants escaped while the aircraft was destroyed by a post crash fire.

The crew was performing a flight from Sewart AFB (Smyrna, Tennessee) to Harrisburg-Intl Airport (Olmsted AFB). After passing over Newburg, the crew did not realize his altitude was too low when the airplane struck the slope of a mountain located 7 miles north of the city. The aircraft was destroyed upon impact and all four crew members have been killed.

Crashed in unknown circumstances into the Mediterranean Sea off Cubelles while on a flight to Barcelona, carrying four passengers and a pilot. As the airplane failed to land in BCN in the evening, SAR operations were conducted and a wheel was found three days later but unfortunately, no trace of the five occupants.

The Douglas C-124 transport plane departed Lajes AFB, Azores on a flight across the Atlantic Ocean to Bermuda-Kindley Field (NWU). The airplane remained on the ground at Bermuda for two hours. It took off again at 01:50 EST, bound for Charleston AFB, SC (CHS). Over the Azalea intersection the pilot checked and was advised that Charleston weather had deteriorated rapidly, presently 15,000 ft broken, visibility 1/4 mile with ground fog. The captain decided enter a holding pattern over Charleston to wait for the sun to burn off the fog. At approximately 06:30 visibility had slightly increased to 1/2 mile in ground fog. Five minutes later a Delta Air Lines flight landed following an ILS approach. The captain decided to carry out a GCA approach and was cleared for this at 06:35. The descent and final approach were normal until just prior to or reaching GCA minimums. At this time the aircraft got too low and clipped the tops of trees that stood about 68 feet above the ground. This caused a fast torque drop and subsequent loss of the no. 3 engine. The co-pilot then declared an emergency. The propeller of engine no.3 was feathered, the flaps were retracted, and an attempt as made to raise the landing gear. Indications were that the right main gear did not retract, and there was damage to the underside of the aircraft. Prior to the emergency the navigator had been asleep (the crew had been on duty for nearly 20 hours). Thus, he had not been monitoring the approach with radar. Also, he made no attempt to assist with dead reckoning, or in any other way to prevent the pilot from becoming lost. At 06:48, the crew became uncertain of their position. They flew for the next 33 minutes in the vicinity of Charleston AFB, at an altitude of only 800 to 1000 feet, because the aircraft would climb no higher even with max power. The aircraft was lost from GCA search radar, apparently due to the low altitude. The passenger and two crew members were killed while seven other occupants were injured.
