200 words Palestinian hijackers attempted to hijack five airliners on September 6 and 9, 1970. Their plan was to fly all of the planes to an abandoned British Royal Air Force (RAF) airfield in Jordan, hold hostages, broker the release of Palestinian prisoners, release the hostages, blow up the planes, and thereby force the world to focus on the plight of the Palestinian people. On September 12, 255 hostages were released from the three planes that landed at Dawsons Field (the RAF base), and 56 were kept to bargain for the release of seven Palestinian prisoners. The group then blew up the airliners.
Unfortunately for the hijackers, their actions greatly alarmed King Hussein of Jordan. Martial law was declared on September 16, and the incident led to civil war between Palestinian forces and the Jordanian army. Although the Jordanians operation was precipitated by the destruction of the airliners on Jordanian soil, tensions had been building between the army and Palestinian forces for some time. King Hussein and the Jordanian leadership interpreted this operation as confirmation that radical Palestinian groups had become too powerful and were a threat to Jordanian sovereignty.
On September 19, Hussein asked for diplomatic intervention from Great Britain and the United States when a Syrian column entered Jordan in support of the Palestinians. On September 27, a truce ended the fighting. The outcome of the fighting was a relocation of much of the Palestinian leadership and fighters to its Lebanese bases. The entire incident became known among Palestinians as Black September and was not forgotten by radicals in the Palestinian nationalist movement. One of the most notorious terrorist groups at the time took the name Black September, and the name was also used by the group led by terrorist Abu Nidal.
