Thani Provinces in Thailand. Thurner's last recorded words were, "Oh, reverser's deployed". Just after, the cockpit voice recorder (CVR) recorded a shuddering sound, followed closely by a snap. Because of the reverser design, the lift on the aircraft's left wing leading edge became disrupted due to the aerodynamic plume formed during the engine's rundown to idle thrust, and resulted in a 25 percent loss of lift, resulting in an aerodynamic stall. The aircraft immediately began a diving left turn. The CVR recorded a second snapping sound, followed by various alerts such as overspeed and master caution, and Welch's last recorded words, which were, "Jesus Christ," in response to the rapid rolling sensation, followed by "here, wait a minute", as he shut down the engine, and then, "damn it". Following this, the CVR recorded an increase in background noise, followed by several loud bangs. Maneuvering overloads produced by the pilots' attempts to regain pitch control, in combination with the velocity during the dive, already had exceeded the aircraft's structural limits, and destroyed the weakened rear fuselage, taking the rest of the damaged flight surfaces with it. The loss of the tail caused further negative loading of the wings as the airplane nosed over vertically, reaching a recorded speed of Mach 0.99 (The highest value onboard sensors were capable of recording), breaking the sound barrier. At that point, the wings failed and sheared off at the trailing edges, engulfing the remains of the falling aircraft in flames before impacting mountainous wooded terrain and exploding. Most of the wreckage was scattered over a remote forest area roughly one square kilometre in size, at an elevation of , in what is now Phu Toei National Park, Suphan Buri. The wreckage site is about north-northeast of Phu Toey, Huay Kamin (), Dan Chang district, Suphan Buri province, about northwest of Bangkok, close to the Burma-Thailand border. Rescuers found Welch's body still in the pilot's seat. Recovery Volunteer rescue teams and local villagers looted the wreckage, taking electronics and jewellery, so relatives were unable to recover personal possessions. The bodies were taken to a hospital in Bangkok. The storage was not refrigerated and the bodies decomposed. Dental and forensic experts worked to identify bodies, but twenty-seven were never identified. Speculation circulated that a bomb may have destroyed the aircraft, largely due to eyewitness reports of the large fireball surrounding the aircraft that had resulted from the
