That is not true. Most of the engine gas exploded when the plane first hit, so there wasn't any gas to burn. Second gas burns at 1800 degrees - Steel melts at 2500 degrees. What makes steel evaporate? The steel did not melt it was evaporated into dust! Thermite was used and was found in the rubble! The explosions happened before the planes hit, then a controlled demolition brought them down. You seem intent to blame this episode on some Muslims. You cannot prove that Muslims did this, I know you can't! But this is what the enemy wants us to do, to argue over inconsequential details instead of uniting and working constructively to end In-Justice throughout the globe.
