Avianca flight AV203, a Boeing 727, crashed near Bogot , Colombia, following the in-flight detonation of an explosive device, killing all 107 occupants. Flight AV203 departed Bogot  at 07:11 for a flight to Cali, Colombia. While climbing through FL130, a improvised explosive device detonated in area under seat number 14F. The empty center fuel tank was then compromised and an ignition of fuel vapours inside the tank then set off a further break up of the aircraft. In 1994, an assassin of the Medellin drug cartel, Dandeny Munoz-Mosquera, was convicted in connection with the crash. He allegedly had arranged to place the bomb aboard the aircraft because he believed that two informers who were cooperating with Colombian authorities were on board.
