Edwards AFB

The twin engine aircraft was completing a liaison flight from China Lake on behalf of the US Navy, carrying seven US Navy personnels and two pilots. On final approach in good weather conditions, the aircraft struck the ground in a relative flat attitude about 800 metres short of runway 22, slid for about 200 metres and came to rest. All seven passengers were seriously injured and both crew members (Lt David W. Garnett and Aean Lorenzo Rodriguez) were killed.

The aircraft was used by the NASA to test fuel fire retardant and crashed upon landing without any passengers or crew on board. The aircraft was destroyed by impact forces and a post crash fire.

In flight, the twin engine airplane suffered a wing failure and crashed near Edwards AFB. The aircraft was destroyed and all three occupants were killed.

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.
