Loftleiðir Flight 001 was a Hajj charter flight operated by a Douglas DC-8 which crashed on approach to Colombo, Sri Lanka, on 15 November 1978. The crash killed 183 out of 262 passengers and crew members. The official report by Sri Lankan authorities determined the probable cause of the crash to be the failure of the crew to conform to approach procedures; however, American and Icelandic authorities claimed faulty equipment at the airport and air traffic control errors as the reasons for the crash. It was the second-deadliest aviation accident in 1978, behind Air India Flight 855.
