Supply

During the roll out, the left landing gear collapsed, resulting in substantial damage to the aircraft. Because of the remote location, the aircraft was declared not salveageable Nov 24, 1961.

Crashed on takeoff while in support of Operation Deep Freeze 1962. While taking off from the skiway at Wilkes Station Antarctica, the Neptune caught fire and crashed. Of the nine men on board, only four survived. The previous landing had been so violently rough that it had broken loose the 400 gal internal tank in the bomb bay and the 4" filler pipe was spewing out raw fuel running down the bottom of the plane on take-off. At the ignition of the JATO on the t/o run, it acted like a Roman Candle. With the burning of the fiberglass tail cone, all of the acrid smoke was drawn right up to the cockpit and the pilots were blinded. They tried to return to the field and just couldn't make it. The pilot managed to level the wings before they hit and that saved some of the guys. 5 killed, 4 injured.

On behalf of the CIA, the crew was engaged in a supply dropping mission to the General Vang Pao's Hmong Army. While flying at low height, the pilot-in-command made a sharp turn when a wingtip struck the ground, causing the aircraft to crash. All six occupants were killed, among them three CIA employees, David W. Bevan, Darrell A. Eubanks, and John S. Lewis.

Engaged in a supply mission, the pilot was approaching the drop zone when he realized he was facing a mountain. He reduced the engine power in an attempt to make an emergency landing when the airplane crash landed on the slope of a snowy mountain an altitude of 5,100 meters. On impact, a fuel tank was broken and the aircraft came to rest in flames. All five crew members were uninjured while the aircraft was destroyed.

The twin engine aircraft struck the slope of Mt Meru while on a supply mission. The pilot, sole on board, was killed.

The crew was involved in a supply mission to Kuomintang guerrillas in east Burma. While flying at low height, the four engine aircraft was shot down by the pilot of a Burma Air Force Hawker Sea Fury. Two crew members were able to bail out and were later recovered. Out of control, the Privateer crashed in the jungle located in a mountainous region of Doi Tung. Four other crew members were killed. The Burmese Hawker Sea Fury registered UB-466 was hit by return fire and crashed shorty later, killing its pilot Noel Peters.

The crew encountered elevator control problems and elected to make an emergency landing in the Plain of Jars when the airplane went out of control and crashed near Phônsavan. Two crew members were killed while the third occupant was injured.

Upon landing at McMurdo Sound-Williams Field, the four engine airplane struck a snowbank, causing the landing gear to collapse. The aircraft went out of control, lost its left wing and both left engines before coming to rest. All 23 occupants were uninjured. The flight was completed on behalf of the 8th Oceanographic Development Squadron of the US Army.

The crew was completing a supply mission to the Swiss Dhaulagiri Expedition in the Himalaya Mountain Range and was leaving the Dambusch Pass to return to his base at Pokhara when the airplane crashed on takeoff. The right wing and the propeller were bent. While both crew members were uninjured, the airplane was abandoned in situ. Swiss people returned on site (5,200 meters high) in 1998 to recover the airplane that should repatriated in Switzerland. It is believed that a technical issue was the cause of the accident.
Crew:
Ernst Saxer, pilot,
Emil Wick, copilot.

The crew was completing a supply mission to Beardmore Glacier and elected to land in whiteout conditions when the airplane struck the icy ground and crashed. Both pilots were rescued five days later and the aircraft was abandoned in situ.
