I thought the original theory of bundled high voltage wires arcing inside the fuel tank was bogus from the get-go.

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.

"such as by an impact, or warhead detonation pressure wave"...or pressurized in a heated space...like a centerline fuel tank used to cool air conditioning pacs taken to 13,000 feet.
