During the Dawson's Field hijackings in 1970, terrorists released 88 hostages while retaining mostly Jewish and Israeli individuals until September 25.
On September 11, 1970, members of the Popular Front for the Liberation of Palestine (PFLP) released 88 of the hostages they had seized earlier at Dawson's Field airstrip in Jordan. The group had hijacked multiple commercial airplanes and diverted them to the remote desert landing strips, demanding the release of Palestinian prisoners in Israeli jails. While many hostages of various nationalities were allowed to depart, those identified as Jewish or Israeli citizens were held back. This tactic aimed to maximize political impact and draw international attention to the Palestinian cause. The remaining hostages endured harsh desert conditions until they were finally freed on September 25 after negotiations. The Dawson's Field incident marked a turning point in international aviation security and counterterrorism policies.
