There is always a variable that cannot be reproduced. But it’s funny how quickly people want to disregard any test that doesn’t support their thesis-—which has already been disproved.
I'm not disregarding anything pertinent. I'm stating a simple fact of the chemistry of combustion. You can't have explosive combustion of kerosene without oxygen. Oxygen doesn't exist in sufficient quantities at a pressure altitude of 12,000'-14,00' msl to allow for explosive combustion of kerosene.
In order to get kerosene vapors to achieve explosive combustion at that altitude it must be compressed. This is precisely what happens inside a jet engine.
Since the center fuel tank, and, in fact, all fuel tanks on all aircraft are vented to the outside ambient pressure in order to allow for fuel and tank expansion and contraction as the aircraft ascends and descends, where did the oxygen inside the tank come from that allowed the vapors in the tank to achieve explosive combustion? It's a really simple question, and one that nobody, not the CIA, the FAA, the FBI, the NTSB, none of them, and certainly not "Mythbusters". has answered.
You can parrot all the so-called answers from the FBI, CIA, FAA, NTSB (and Mythbusters) as loud and proud as you want, but it still doesn't answer this simple question of chemistry.....
