Lauda 004 INFORMATION:
At the time of the accident, Lauda Air operated three weekly flights between Bangkok and Vienna.[6] On 26 May 1991, at 23:02 ICT , flight NG004 (originating from Hong Kong's Kai Tak Airport ), a Boeing 767-3Z9ER , took off from Don Mueang International Airport for its flight to Vienna International Airport with 213 passengers and ten crew, under the command of American Captain Thomas J. Welch (48) and Austrian First Officer Josef Thurner (41).[5] :4[7] [8] [9] [10] [11] At 23:08, Welch and Thurner received a visual warning indicating that a possible system failure would cause the thrust reverser on the number one engine to deploy in flight. Having consulted the aircraft's quick reference handbook, they determined that it was "just an advisory thing" and took no action.[1]
At 23:17, the number one engine reversed thrust while the plane was over mountainous jungle terrain in the border area between Suphan Buri and Uthai Thani Provinces in Thailand. Thurner's last recorded words were, "Oh, reverser's deployed".[12] [5] :55 Just after Thurner said this, the cockpit voice recorder (CVR) recorded a shuddering sound, followed by a metallic snap. Lift on the aircraft's left side was disrupted due to the reverser deployment, and the aircraft immediately began a diving left turn. The CVR recorded a second metallic snapping sound, followed by various alarms and Welch's last recorded words, which were, "Jesus Christ!" followed by "here, wait a minute", and then, "damn it!" Following this, the CVR recorded an increase in background noise, followed by several loud bangs, and then stopped recording. The aircraft went into a diving speed of Mach 0.99, and may have broken the sound barrier . The aircraft broke up mid-air at 4,000 feet (1,200 m).[13] Most of the wreckage was scattered over a remote forest area roughly one square kilometre in size, at an elevation of 600 m (2,000 ft), in what is now Phu Toei National Park , Suphan Buri. The wreckage site is about 6 kilometres (4 mi; 3 nmi) north-northeast of Phu Toey , Huay Kamin , Dan Chang District , Suphan Buri Province ,[5] about 100 kilometres (62 mi; 54 nmi) northwest of Bangkok , close to the Burma-Thailand border.[6] [14] Rescuers found Welch's body still in the pilot's seat.[15]

Derry 006 INFORMATION:
Derry Airlines Flight 006 is a domestic flight from Boston to Halifax via Derry, which crashed after going to a cruise altitude of 19,000 ft due to a reverse thruster in engine #2 deployed mid-air, which led into the plane spiralling all the way down and breaking up, then exploding cargo doors, then a hole in the cabin, resulting into the 2001 Volcano of Ash Eruption, killing 832 people on the ground and ending up killing all 173 occupants on the plane.
