The Aero Spacelines 377MGT was a converted Boeing Stratoliner. Prototype N111AS first flew on March 13, 1970. In the following period flight testing was carried out, a.o. at Edwards AFB. The accident occurred during the sixth takeoff of Flight Number 12 following the scheduled shutdown of the engine number one at about 109 knots IAS. The takeoff was being made on runway 22 and the wind was from approximately 200 degrees at about 10 knots. Rotation occurred at about 114 knots and several seconds after rotation, according to one witness, the aircraft turned and rolled to the left, settling as it did so. The left wingtip subsequently contacted the ground, causing a severe yaw. The forward fuselage struck the ground, causing the flight deck to be destroyed. The test flight was under FAR Part 25 certification program.

The approach to Pellston-Emmet County was initiated in limited visibility due to clouds. On final, the crew failed to realize his altitude was too low when the airplane struck trees and crashed in flames few miles short of runway threshold. The aircraft was destroyed and all six occupants were killed, among them Walter Reuther, President of the American Union of Workers in the Automotive Industry.

Prior to takeoff, the local controller offered pilot choice of runways 01 or 28. The crew decided to takeoff from runway 01. During the takeoff roll, the airplane was caught by strong winds and control was lost. The airplane veered off runway, lost its undercarriage and came to rest in flames. Both pilots were injured and the aircraft was destroyed by fire.

On final approach to Barrow, the crew failed to realize the configuration was wrong. Few dozen yards short of runway threshold, the airplane struck a snowbank, lost its undercarriage and its left wing before bursting into flames. All three crew members were injured and the aircraft was destroyed.

Shortly after takeoff from runway 30 at Hamilton AFB (Novato, CA), the crew was cleared to climb at his discretion, following heading 360 till 2,600 feet then heading 340. Few seconds later, the airplane struck trees and crashed on a mountain slope located eight miles from the airbase. The aircraft was totally destroyed by impact forces and a post crash fire. A passenger was seriously injured while 13 other occupants were killed. The crew from the 26th Division was completing a flight to Spokane, Washington. At the time of the accident, weather conditions were considered as good with three cloud layers at 900, 15,000 and 25,000 feet, a visibility of about 8 miles and a light wind from 340 at 2 knots.

While in cruising altitude, the right engine lost power. Unable to maintain the assigned altitude, the crew decided to attempt an emergency landing. The airplane belly landed in a prairie and slid for dozen yards before coming to rest. All 12 occupants were uninjured while the aircraft was damaged beyond repair.

Shortly after takeoff from Morris Airport, while in initial climb, the pilot informed ATC about an engine failure and was cleared to return for an emergency landing. On final, the airplane stalled and crashed in a field located short of runway threshold. The aircraft was destroyed and the pilot was seriously injured.

The airplane departed McDill AFB, Florida, on a flight to Langley AFB. After a technical stop at Shaw AFB located in Sumter, the crew continued bound to the north. About 20 minutes prior to its arrival at Langley AFB, while in cruising level, the airplane collided with a USAF Douglas TA-4F Skyhawk. Both aircraft went out of control, entered a dive and crashed in the region of Weldon. All six crew members on both aircraft were killed.

The aircraft was being operated as an international cargo flight by Compania Ecuatoriana de Aviacion. The accident occurred during the initial climb, following an instrument takeoff on Runway 27R at Miami International Airport. The flight was en route,from Miami to Panama City, Panama, the first leg of a flight which was to terminate at Quito, Ecuador. The two pilots, the only occupants of the aircraft, were killed, and the aircraft was demolished by impact and post impact ground fire. The crew first requested a takeoff clearance at 0621 but because fog reduced visibility to one-eighth mile, the tower controller delayed issuance of the clearance until 0722 when the visibility was reported to be one quarter mile, the visibility minimum the pilot had stated he needed for takeoff. The crew's acknowledgment of this clearance was the last recorded transmission from the flight. Following liftoff, the aircraft was observed flying in a level flight attitude at an altitude of approximately 50 feet near the western end of Runway 27R, which was 10,500 feet long. The landing gear was retracted. As the observers watched the aircraft, they saw the nose drop slightly, check, and then the aircraft descended to earth. Impact occurred 279 feet north and 230 feet beyond the western end of the takeoff runway. The aircraft continued 89 feet beyond the initial impact point, struck a concrete abutment and burned.

On final approach to Tallahassee Airport by night, the pilot failed to realize his altitude was insufficient when the airplane struck tree tops and crashed few hundred yards short of runway threshold. All four occupants were seriously injured and the aircraft was destroyed.
