Lauda Air Flight 004
Lauda Air Flight 004 was a scheduled international passenger flight from Kai Tak, Hong Kong, China to Wien-Schwechat International Airport, Vienna, Austria via Don Mueang International Airport, Bangkok, Thailand. On 26 May 1991, during it's Bangkok to Vienna leg, the Boeing 767-3Z9ER operating the route suffered from a rare uncommanded thrust reverser deployment while flying over the Burma-Thai border and crashed into wooded terrain about ~94 nautical miles northwest of Bangkok, killing all 213 passengers and 10 crew members on board. It is the first and deadliest loss involving the Boeing 767, and as of 2022, Thailand's worst aviation accident.
