When did the airport disaster which involved Jacob Veldhuyzen van Zanten as the captain happened?
Tenerife airport disaster On March 27, 1977, two Boeing 747 passenger jets, KLM Flight 4805 and Pan Am Flight 1736, collided on the runway at Los Rodeos Airport (now Tenerife North Airport), on the Spanish island of Tenerife, Canary Islands, killing 583 people in the deadliest accident in aviation history.
BOAC Flight 712 BOAC Flight 712 (callsign "Speedbird 712") was a British Overseas Airways Corporation service operated by a Boeing 707-465 from London Heathrow Airport bound for Sydney via Zurich and Singapore. On Monday 8 April 1968, it suffered an engine failure on takeoff that quickly led to a major fire. The engine fell off the aircraft in flight. After the aircraft had made a successful emergency landing, confusion over checklists and distractions from the presence of a check captain contributed to the deaths of five of the 127 on board.
