The Crash of JAL 123
From Nippon.com:
On August 12, 1985, the crash of a Japan Airlines Boeing 747 in central Japan resulted in 520 fatalities. It was Japan’s deadliest air accident, as well as the deadliest air disaster in history involving a single aircraft and no additional deaths on the ground.
A sad tale. The TV program Mayday did an episode on this crash it is worth the watch. The fact that four people managed to survive is frankly amazing.
