El Al Flight 426 hijacking
El Al Flight 426 was an El Al passenger flight hijacked on 23 July 1968 by three members of the Popular Front for the Liberation of Palestine (PFLP), setting off a wave of hijackings by the PFLP. Scholars of political science and terrorism studies have characterized the hijacking of the El Al Flight 426 as significant in the advent of modern international air terrorism. According to David C. Rapoport, Professor Emeritus of Political Science at University of California, Los Angeles (UCLA), the modern wave of left-wing terrorism began with the hijacking of the El Al Flight 426 in the context of the political unrest of 1968.
