Seriousl question - planes are aluminum, thus non-ferrous. "Jet fuel" is essentially higher refined kerosene. Kerosene has very low volatility. What was the source of immediate ignition? If the PA plane vaporized hitting dirt, how did a soft aluminum plane make it thru hard reinfoced concrete, steel etc... And have a Hollywood esque fireball exit on the opposite side? Thats like throwing a water balloon against your house and having it blow out the other side
