Investigation Summary
The incident began when Clay Thomas seized control of the Boeing 727 after its departure from San Francisco International Airport. Thomas claimed to possess an explosive device and ordered the flight to Oakland, California, where he intended to refuel for a long-distance flight to Cuba. During the standoff on the ground in Oakland, the flight crew successfully negotiated the release of all passengers and cabin crew members. However, the sight of police vehicles near the aircraft caused Thomas to panic, leading him to order an immediate takeoff before fueling was complete. Once airborne, the pilots convinced Thomas that the aircraft lacked sufficient fuel to reach Cuba, necessitating a second stop at Stapleton International Airport in Denver. After landing in Denver and waiting for approximately 90 minutes, the three cockpit crew members executed a coordinated escape by jumping from the open cockpit windows to the tarmac, a height of approximately 18 feet. All three crew members sustained injuries during the jump. Left alone on the aircraft with no hostages, Thomas surrendered to FBI agents five minutes later. No bomb was found.
Final Conclusions
The event was concluded as a successful resolution of a hijacking through crew initiative. The hijacker, Clay Thomas, was taken into custody by the FBI shortly after the crew's escape. The injuries to the crew were the only physical casualties of the event.
