Blimey I must be getting old was it really 40 years since the Tenerife airport disaster.
The Tenerife airport disaster was a fatal runway collision between two charter Jumbo Boeing 747's of Pan Am named Clipper Victor and KLM's The Rhine on Sunday March 27 1977 at Los Rodeos Airport on the Spanish island of Tenerife, one of the Canary islands.
The crash killed 583 people, making it the deadliest accident in aviation history. (and it was on the ground)
Robina van Lanschot, who was with the Dutch tour company who had chartered the KLM flight, decided she had seen her passengers through to the Canaries and decided to call it a day and stay overnight with her boyfriend in nearby Santa Cruz. This decision certainly saved her life. She tried to persuade her two best friends to get off at Tenerife too, but they would not.
