El Al Flight 432 attack
A greater disaster was averted when Mordechai Rahamim, an undercover Israeli security agent stationed on the plane, opened fire at the attackers and killed the terrorist leader.Leaping out of a vehicle parked near a hangar, two terrorists opened fire with AK-47 assault rifles,[3][4] and another two tossed incendiary grenades as well as dynamite that failed to explode[citation needed].During the shootout, Rahamim killed the squad leader[citation needed], and the battle eventually ended when the Swiss security forces arrived at the scene.[citation needed] On 27 November 1969, the trial of Rahamim and the three terrorists, Mohamed Abu Al-Haija, Ibrahim Tawfik Youssef and Amina Dahbour, began in Winterthur, Switzerland.[citation needed] During the trial, Israel was forced to admit for the first time that security personnel accompany Israeli flights, to prevent hijackings and terrorism from happening in the air.
