Air Crash Investigations: Tenerife Airport Disaster, the World's Deadliest Plane Crash Ever

On Sunday, March 27, 1977 KLM Flight 4805 and PANAM Flight 1736 both approached Las Palmas Airport in the Canary Islands, when a terrorist's bomb exploded on the airport. Both flights were diverted to the neighboring island of Tenerife. After Las Palmas Airport reopened first KLM Flight 4805 was cleared for takeoff, a few minutes later PANAM 1736 was cleared. Due to a number of misunderstandings both aircraft collided on the runway of Tenerife Airport during takeoff, killing 583 people.
