2003 Ukrainian Cargo Airways Ilyushin Il-76 accident
The aircraft had no proper seating, and there were only folding chairs in the cabin, with people "crammed onto benches and on the floor."[2] About 45 minutes after takeoff from Kinshasa, at an altitude of 10,000 feet (3,000 m), the cargo door of the Ilyushin Il-76 suddenly opened, blowing many passengers out of the aircraft.Aviation officials and western diplomats in Congo estimated that at least 170 people were killed in the incident.Information minister Kikaya Bin Karubi told Reuters that the Congolese Air Force and Army were investigating to determine whether the accident was the result of human error or a mechanical problem.The pilot suggested that the door had opened either after one of the passengers tinkered with its controls, or because of a computer glitch.
