Which aviation disaster occurred in 1977 involving two Boeing 747s?

The Tenerife Airport Disaster is the correct answer because it involved a tragic collision between two Boeing 747 aircraft, operated by KLM and Pan Am, at Los Rodeos Airport (now Tenerife North Airport) in the Canary Islands on March 27, 1977. This disaster remains the deadliest aviation accident in history, resulting in the deaths of 583 people.

The collision was precipitated by a series of miscommunications, misunderstandings, and compounded by dense fog, which severely reduced visibility at the airport. The KLM flight began its takeoff roll without proper clearance while the Pan Am aircraft was taxiing on the same runway. The sheer number of passengers on the two aircraft — 248 on the KLM flight and 396 on the Pan Am flight — coupled with the unfortunate circumstances, led to the catastrophic outcome.

In contrast, the other events listed occurred in different contexts or involve other types of incidents. Air India Flight 182 was a bombing incident in 1985, Pan Am Flight 103 was a bombing over Lockerbie in 1988, and Korean Air Flight 007 was shot down in 1983 after straying into Soviet airspace. Each of these incidents is significant in aviation history but does not involve a collision
