report Flight 401 departed New York on Friday, December 29, 1972, at 21:20
EST, with 163 passengers and 13 crew members aboard. As Stockstill started another turn, onto 180°, he noticed the discrepancy. The following conversation was recovered from the flight voice recorder later: {{Blockquote|{{dialogue|S=Stockstill|L=Loft Less than ten seconds after this exchange, Flight 401 crashed. The location was west-northwest of Miami, from the end of Runway 9L. The aircraft was traveling at when it hit the ground. With the plane in mid-turn, the left wingtip hit the surface first, then the left engine and the left landing gear, making three trails through the
sawgrass, each wide and more than long. When the main part of the fuselage hit the ground, it continued to move through the grass and water, breaking up as it went.
Crash sequence The TriStar's port outer wing structure struck the ground first, followed by the number1 engine and the port main undercarriage. The disintegration of the aircraft that followed scattered wreckage over an area long and wide in a southwesterly direction. Only small fragments of metal marked the wingtip's first contact, followed further on by three massive swaths cut through the mud and sawgrass by the aircraft's extended undercarriage before two of the legs were sheared off. Then came scattered parts from the number 1 (port) engine, and fragments from the port wing itself and the port
tailplane. About from the wingtip's initial contact with the ground, the massive
fuselage had begun to break up, scattering components from the underfloor
galley, the cargo compartments, and the cabin interior. At along the wreckage trail, the outer section of the starboard wing tore off, gouging a crater in the soft ground as it did so. From this point on, the breakup of the fuselage became more extensive, scattering metal fragments, cabin fittings, and passenger seats widely. The three major sections of the the most intact of which was the tail lay in the mud towards the end of the wreckage trail. The fact that the tail rear fuselage, number2 tail-mounted engine, and remains of the finally came to rest substantially further forward than other major sections, was probably the result of the center-mounted number2 engine continuing to deliver thrust during the actual breakup of the aircraft. No complete cross-section of the passenger cabin remained, and both the port wing and tailplane were demolished to fragments. Incongruously, not far from the roofless fuselage center section with the inner portion of the starboard wing still attached, lay a large, undamaged and fully inflated rubber dinghy, one of a number carried on the TriStar in the event of an emergency water landing. The breakup of the fuselage had freed it from its stowage and activated its inflation mechanism. == Rescue and aftermath ==
