Note for non-pilots: The airspeed, altitude and rate of climb instruments on an aircraft are all variants of simple air pressure sensors. The readings can be (and were) analyzed back to the actual air pressures causing those readings. The readings of the last second of the flight recorded an air pressure (overpressure) higher than any that exists in nature and could only have been caused by an explosion external to the plane. Those readings could not even have been recorded by the recorder if an explosion of the center fuel tank was the initial event, since the explosion itself would have instantaneously severed the wires connecting the several sensors with the data recorder, which is located in the rear of the plane.
It is still depicted graphically on their site here: http://www.ntsb.gov/events/TWA800/exhibits/Ex_10A.pdf (pg 52)
"the data perfectly recorded an overpressure created by an ordnance explosion near the front of the plane."
Based on a comparison to what data? I'm not saying there isn't data out there showing what an overpressure from an ordnance explosion looks like on an FDR...I'm just wondering where it is. Interestingly, every parameter recorded by the FDR spikes in the last second it is recording. Not just the pressure instruments. That includes things like the mic switch position, the flight control positions, aircraft heading etc, which might indicate an electrical surge to the FDR causing a faulty record as it shut down.
