Aircraft hijacking

Aircraft hijacking (also known as Skyjacking) is the take-over of an aircraft, by a (usually) armed person or group. Unlike the hijacking of land vehicles, it is usually not perpetrated in order to rob the cargo. Rather, most aircraft hijackings are committed to use the passengers as hostages and to obtain transport to a location. In the September 11 Terrorist Attack, 2001, the use of hijacked planes as suicide missiles changed the way hijacking was perceived as a security threat.

One task of airport security is to prevent hijacks by screening passengers and keeping weapons off aircraft.

Hijackings for hostages have usually followed a pattern of negotiations between the hijackers and the authorities, followed by some form of settlement -- not always the meeting of the hijackers' original demands -- or the storming of the aircraft by armed police or special forces to rescue the hostages. Previous to September, 2001, the policy of most airlines was for the pilot to comply with hijackers' demands in the hope of a peaceful outcome. Since then, policies have reversed course, in favor of arming and armoring the cockpit.

The first recorded aircraft hijack was on February 21, 1931, in Arequipa, Peru. Byron Rickards flying a Ford Tri-motor was approached on the ground by armed revolutionaries. He refused to fly them anywhere and after a ten day stand-off Rickards was informed that the revolution was successful and he could go in return for giving one of their number a lift to Lima. Most hijackings have not been so farcical. The first hijack of a commercial airliner probably happened on July 16, 1948, when a failed attempt to gain control of a Cathay Pacific seaplane caused it to crash into the sea off Macao.

Since 1947, 60% of hijackings have been refugee escapes. In 1968-69 there was a massive rise in the number of hijacking. In 1968 there were 27 hijackings and attempted hijackings to Cuba. In 1969 there were 82 recorded hijack attempts worldwide, more than twice the total attempts for the whole period 1947-67. Most were Palestinians using hijacks as a political weapon to publicise their cause and to force the Israeli government to releasing Palestinian prisoners from jail.

Airliner hijackings have declined since the peak of 385 incidents between 1967-76. In 1977-86 the total had dropped to 300 incidents and in 1987-96 this figure was reduced to 212.
