The deadliest crash in aviation history

March 27, 1977. At 2:00 in the afternoon, a thick fog rolled into the usually quiet Los Rodeos Airport in Tenerife, in the Canary Islands. On the runway sat two fully loaded jumbo airliners, blanketed in fog. An explosion at a nearby airport had redirected air traffic to the undermanned airfield at Tenerife. Within three hours 583 people would be dead. To explain how it happened, Crash of the Century reconstructs the moments leading up to this terrible tragedy.
