Dawson's Field hijackings
In September 1970, members of the Popular Front for the Liberation of Palestine (PFLP) hijacked four airliners bound for New York City and one for London. Three aircraft were forced to land at Dawson Field, a remote desert airstrip near Zarqa, Jordan, formerly Royal Air Force Station Zarqa, which then became PFLP's "Revolutionary Airport".
