Fatal US hijacking events

The following are the known fatal hijacking events involving a US carrier or a flight arriving or departing the US where at least one passenger was killed. Events since 1970 are included. Events that are not numbered are included because they meet criteria set by AirSafe.com for significant events.

11 June 1971; TWA 727; flight 358; Chicago, IL: While passengers were boarding the aircraft for a scheduled domestic flight to New York's JFK airport, the hijacker, who was not a ticketed passenger, entered the aircraft, killed one of the passengers, and demanded to be flown to North Vietnam. After the passeners were released and the aircraft took off for New York, a US Marshall, who had entered the aircraft prior to departure, apprehended the hijacker.
4 October 1971; Big Brother Aircraft Company; Jacksonville, FL: Two hijackers, commandeered a chartered aircraft that was on a planned flight to Atlanta, and forced the two pilots, as well as a hostage to fly to Cuba. One of the pilost, Brent Downs, convinced the hijackers that the plane needed to refuel, and the plane landed in Jacksonville, FL.

While on the ground, after unsuccessfully negotiating with the FBI to refuel the aircraft, the FBI opened fire on the aircraft. One of the hijackers killed the pilot Downs, his hostage (who was also the hijacker's wife) and himself. The other hijacker surrendered, but was not convicted of hijacking the aircraft.

This event did not involve an airliner, but is included because of the role the FBI played in the hijacking.

5 July 1972; Pacific Southwest 737-200; San Francisco, CA: The aircraft was on a scheduled flight from Sacramento to San Francisco when shortly before landing it was hijacked by two armed men who intended to have the aircraft fly to the Soviet Union. After landing in San Francisco, the aircraft was directed to an isolated part of the airport while the hijackers negotiated with authorities. Later, an armed FBI agent posing as the pilot that would fly the aircraft to the Soviet Union entered the aircraft while, unknown to the hijackers, three other armed FBI agents were able to position themselves near the front entry door. As the three outside FBI agents began to climb the stairs to enter the aircraft, a gun battle broke out which resulted in the deaths of both of the hijackers and one of the 77 passengers. Two other passengers were wounded, but survived. None of the seven crew members were injured.

17 December 1973, Pan Am 747, Rome, Italy: While the aircraft was at the gate loading passengers, a group of terrorists shot at the plane and threw incendiary grenades into the aircraft, killing 30. The terrorists later hijacked a nearby Lufthansa 737.
