Proof Number Three:
It can certainly be argued that any refuting of NTSB CWS findings is by default an argument that something else caused the crash. That the nature of the refuting evidence is also suggestive that some external force is the cause instead of some internal force is highly supportive of missile fire. As seen thus far, there are several interlocking indications of this kind already presented, here. But there are more evidences which deserve consideration, evidences consistent with missile fire. Some of the best evidence is from within the NTSB report itself.
Example One: The CVR offers evidence consistent with a missile attack.
Basic Presumptions: 1) That a dummy-warhead equipped missile would merely penetrate the aircraft as if a bullet, without exploding outright on its own; 2) That a military missile will travel at supersonic speeds; 3) That sound travels in air, a light medium, at slower speeds than impact vibrations in metal, a dense medium; 4) That analysis of the CVR should be consistent with these observations and critical to understanding what happened to Flight 800; 5) That should CVR readings be supportive of missile attack, then there are adequate reasons to suspect this is what happened.
The NTSB report examines the CVR evidence in what appears to be a comprehensive manner, but which upon closer scrutiny, seems an attempt to avoid actual analysis of the audio evidence for clues as to what happens. They go to a great deal of effort to laboriously detail comparisons of Flight 800 CVR data to other crash CVR data where causes were known, in hopes of finding matches or other clues, but fail to do so. Not even the comparison of Pan-Am 103's bomb blast CVR or a known incident of a center wing tank explosion provided anything close to whatever was recorded on Flight 800's tape. This would logically indicate that something other than those causes were involved in bringing down Flight 800, a conclusion the report does not dare to make.
Below is the Captain's radio recording
trace from page 12 of Exhibit 12B. Despite the poor reproductive quality
and the narrow compression of the important final fraction of a second's
worth of sound at the far right of the chart, there are excellent clues
visible. The key area has been enlarged and reproduced in blue, here, with
red and yellow indicators and arrows added to aid the discussion of this
The issue with respect to missile fire is found within the final sound itself. It can be noted that the makeup of the sound appears to be defined as several stages. One missile-fire theory favored by this author calls for a missile to enter the aircraft under the left wing and pierce the fuselage within the protective area of the wing faring just forward of the CWS, where it travels upward and slightly forward, penetrating the passenger cabin floor, and then exiting the aircraft on the right side just ahead of the wing. Following along in the magnified blue version of the signal, above, there is a building stage where the sound initiates but at relatively low signal levels. This could represent a missile penetration in the lower wing area (shown as a red square, above). This is followed by a tremendous increase in signal which has a finite duration (right-pointing arrow and red/yellow square), which could represent the missile penetrating the left fuselage.
This is then followed by a quieter period (first of the two smaller red/yellow rectangles) which could represent the missile within the cargo bay just prior to encountering the cabin flooring. There is then another brief spike (between the two small red/yellow rectangles) of intensity, which could represent the floor penetration itself, followed by another reduced or quiet period (rightmost small red/yellow rectangle), and yet another intensity which could be the exit wound in the airframe (large red/yellow square, left-pointing arrow), followed by a tapering off stage, which could represent damage being done to the right wing faring by debris and departing adjacent skin structures (large red/yellow rectangle) or rocket thrust. Thus we have remarkably equal periods for airframe penetration left and right and similarly equal quieter periods between them and a brief period for floor penetration. Two challenges or proofs to this theory naturally arise.
The first is that these sounds seem rather distinctive in terms of dramatic rise and fall of volume. Certainly, any normal audio recording might be expected to be less clear once an event took place and items within the aircraft began coming apart, but that is not what seems to take place, here. This is because sound travels in a dense medium faster than a light medium. The sound recorded would thus appear to be sound conducted directly to the area of the microphone through the airframe itself, more than 'down the corridor' or outside the aircraft. Some experts have claimed that sound from a CWS explosion would travel at only 400 fps, but a sudden impact with a missile would travel at speeds of 2,000 fps, or faster, dependent on missile speed. This would seem supportive of clear and distinctive recording of event sequences as described, here.
The second is that if we are to believe a missile penetrated the aircraft at supersonic speeds, it would be required that the sound produced, especially if recorded through inductance of the shock waves through the metal as described above, would time out correctly: the sound would last no longer than it would take for the missile to penetrate the aircraft and exit the other side. This can be calculated, since the recording times are solidly known, and the distances involved are relatively known (an estimate based on presumed angle of attack diagonally through the airframe and the diameter of the aircraft body at point). This is what the results look like:
The length of time between the presumed entrance and exit on the chart (between the two red arrows) maps out to approximately .02 seconds, a nice round number for our purposes. The approximate distance based on aircraft diameter and an angled path is approximately 40', another round number. Variances of this data should not significantly affect results, since a supersonic missile can travel at anywhere from Mach 1.5 to 2.5, depending on a wide variety of missiles and situations. Anything in that window is a clue highly suggestive of missile fire. Further, actual Mach speeds depend on altitude and temperature variables, so there is no single precise speed which is, say, Mach 2.0
While the Captain's mic seemed to pick up useful sounds with respect to this analysis, it is important to note that none of the other microphones followed suit. Since the microphones are mounted on pilot headsets and and are somewhat directional in order to better pick up the voice of the officer speaking in lieu of background noise, the angle of sensitivity would be dependent upon which direction the person was facing at the time. It can be presumed that perhaps the Captain was likely facing a sympathetic direction while the others were not.40' in .02 sec = 4,000' in 2 seconds = 2,000 fps
Summary: The sound recorded fits the profile of a missile penetration of the aircraft, the shock wave of which was transmitted at about 2,000' per second through the airframe to the microphone -- just as claimed would be the case by technical advisors.
