Don't you know it's a proven scientific fact that nanothermite ignites at 430c?
That's the difference!
The jets were used to ignite the thermite paint, which then quickly burned right through the buildings down to the ground. You can see the nanosmoke pouring out all the way down.
That's why the towers collapsed almost instantly after the plane impacts, and faster than freefall speed.
