Zürich was snowed under on February 18, 1969. In the afternoon, a white VW stops at a parking space on the edge of Kloten Airport. Three men and one woman, activists of the PFLP-People's Front for the Liberation of Palestine, are inside. Around 5.30 pm, a Boeing 720 B of the Israeli company El Al is in front of the vehicle, waiting to take off for Tel Aviv. Two activists then get out of the VW and fire automatic weapons towards the cockpit: six passengers are wounded, the pilot will die 5 weeks later in a hospital in Zurich. The Israeli security guard on board manages to get out of the plane and cross the fence that separates it from the Palestinians. He shoots and kills one of the PFLP militants.The Israeli officer and the Palestinian commando are arrested. The Swiss authorities "strongly condemn" the actions of the assassins. December 1969, end of the trial: the three Palestinian militants are sentenced to 12 years in prison, the Mossad officer is acquitted. Demonstrations follow in Switzerland. A rift is formed between pro-Israeli and pro-Palestinian activists. Switzerland is accused of siding with Israel. Shocked by this situation, Francis Reusser, a filmmaker, and Jean-Pierre Garnier, a young director at TSR, contact the head of Fatah in Geneva. He is willing to support an information project - a report and a film - carried out with Fatah activists in the refugee camps in Jordan.
