March 27, 1977
Tenerife, Canary Islands
Pan American,  Flight 1736 / KLM, Flight 4805
Boeing B-747-121 / Boeing B-747-206B

Both aircraft were diverted to Tenerife because of a bombing at Las Palmas Airport. After an
extended delay, both planes were instructed to back track up the runway. The KLM plane
reached its takeoff point while the Pan Am plane was still on the runway. The Pan Am plane
continued up the runway missing the taxiway turnout. There was heavy fog on the runway.
The KLM plane began its takeoff roll without permission with the Pan Am plane still on the
runway. The KLM plane hit the Pan Am plane just as it was taking off. Both planes burst into
flames. KLM 234 + 14 crew, Pan Am 326 + 9 crew killed.
