The crew was completing a transpacific flight from Sangley Point AFB to Whidbey Island with probable en route stops in Japan and Alaska (Elmendorf or Ladd AAF). While in cruising altitude, the airplane struck the slope of Mt Fairweather located approximately 123 miles northwest of Juneau. As the aircraft failed to arrive at Whidbey Island NAS, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the 14 crew members was found. In 1982, the wreckage was found in an isolated area.

Crashed on landing at Otis AFB and came to rest in flames. There were no casualties but the aircraft was destroyed by fire.

The crew was completing a local training flight out from Jacksonville-Towers Field NAS. While approaching the airbase from the east, the airplane collided with a USN Vought RF-86G Crusader registered 146864 and carrying one pilot. Following the collision, both aircraft dove into the ground and crashed in Jacksonville Beach, some 17 miles east of the airfield. All six occupants on both aircraft were killed.

En route from Minneapolis-St Paul Airport to Willow Grove NAS, an engine failed. The crew was cleared to divert to Lock Haven for an emergency landing. In unknown circumstances, the airplane came to rest in flames and burned out. There were no casualties.

The crew was engaged in an anti-guerilla survey flight when he encountered an unexpected situation and was forced to attempt an emergency landing. The airplane crash landed on Bandeira Peak located in the Caparaó National Park. All three crew members were injured while the aircraft was damaged beyond repair.

The crew departed Lorient-Lann Bihoué Naval Air Station on a maritime patrol flight on behalf of the 24F Group. En route, in unknown circumstances, the airplane crashed into the Iroise Sea, some 40 nautical miles off the Ar-Men lighthouse, Britain. All 13 crew members were killed.
