In order to get Jet-A fuel to explode it has to be agitated.

No, it has to be compressed, thereby enriching the oxygen mixture.

You cannot just put a match to it, it won’t burn.

Kerosene will barely burn at sea level. If you throw a match into a pan of kerosene, 9 times out of 10 it will go out. That's because the vapors aren't explosive and cannot achieve explosive combustion, even at sea level pressure.

So what caused the fuel to explode?

Whatever caused the airplane to explode. I don't know what was the cause, but quite obviously fuel vapor wasn't it......

Thank you for correcting me. ;-)

I knew it was something like that, but I just could not put it into words.
