(FDR) – The device records 18 aspects of the flight, such as altitude and heading.Witnesses to the Explosion – 200 witnesses that were likely to have spotted the burning aircraft after it had begun to break up.Reconstruction of the debris - Portion of the airplane have been reconstructed, including the CWT, the passenger cabin above the CWT, and the air conditioning packs and associated ducting beneath the CWT. The reconstruction shows outward deformation of the CWT walls and deformation of the internal components of the tank that are consistent with an explosion originating within the tank. A close scientific examination and analysis of almost 200 holes, slits, punctures and penetrations.Aircraft Engineers.Flight and miscellaneous tests – Cooling of the air conditioning pack bay and temperature of fuel tanks are measured in flights similar to that of TWA800.In July 1997, a hearing of the NTSB’s investigation was conducted (NTSB hearing summary 1997). NTSB officials provided vital information regarding the flight path and the sequence of the aircraft’s explosion. The NTSB showed and concluded that the aircraft had an explosion came from around the Center Wing Fuel Tank (CWT), but was unable to find the source of ignition that caused the explosion. They also proved that TWA flight 800 was not downed by a missile or by a bomb explosion. 2.3 SEQUENCE OF BRAKEUPAccording to the NTSB’s investigators (NTSB hearing summary 1997), the explosion of TWA 800 was divided into three-stage sequence. The explosion was the first stage. The stage shows that the explosion released wreckage from in and around the center fuel tank. Secondly, the separation of the forward fuselage from the rest of the aircraft. Finally, the continuing flight and eventual breakup and descent of the remainder of the aircraft.Based on the reconstruction of the debris (McKenna, 1997, p32), NTSB investig...
