The Security Council expressed extreme concern at the crash of United Nations Flight 806 and at the disappearance of other aircraft over Angolan territory controlled by UNITA. It deplored the lack of co-operation in clarifying the circumstances of the incident and permitting a United Nations search and rescue mission. The Council demanded that Jonas Savimbi, the leader of UNITA, respond immediately to appeals from the United Nations to search and rescue possible survivors of Flight 806.
