I thought the original theory of bundled high voltage wires arcing inside the fuel tank was bogus from the get-go. I'm no expert, and I didn't sleep in a Holiday Inn Express last night, but, there would probably not been enough oxygen inside the tank to sustain an explosion. Jet fuel, I believe, is primarily kerosene, not gasoline....

Correct. An explosion from "fumes" has to occur when the 'fume/air' mix is precisely X (I don't know what it is for kerosene fumes.)

In the case of natural gas, though, the mix has to be precisely 7% IIRC.

So there are a LOT of co-incidences which must have happened--besides the fact that there was NO OTHER Boeing plane on which this EVER happened.

There is no HIGH voltage wiring in the fuel tank.

And yes, it's essentially kerosene, and demonstrably will not ignite unless the temperatures are way above ambient, or else the fuel has been turned into an aerosal, such as by an impact, or warhead detonation pressure wave.
