Pakistan International Airlines Flight 404 was a Fokker F27 Friendship that disappeared shortly after takeoff on 25 August 1989. The aircraft presumably crashed somewhere in the Himalaya Mountains, Pakistan. All 54 people on board were lost and presumed dead. Disappearance At 07:36, a domestic scheduled passenger flight of Pakistan International Airlines took off from the northern city of Gilgit, Pakistan on its way to the national capital Islamabad. One of the pilots of the aircraft made a routine radio call at 07:40; this was the last communication with the aircraft. The aircraft is thought to have crashed in the Himalayas, but the wreckage has never been found. Aircraft The aircraft was a Fokker F27-200 Friendship turboprop airliner, c/n 10207, built in 1962 and registered as AP-BBF.
