Sorry Bub, but you proved to me just how stupid you are when you used the "jet fuel can't melt steel" theory.
Hint - nobody says that. Never did. But if you want to claim so, go right ahead, I'll be right here laughing at you.
But you are right about the gravity thing. The debate is about the true amount of time it took for 7 to fall. "True Believers" will say 8.2 seconds. Others, that take the time to look at other evidence, will say much longer - I believe around 18 seconds to be what seismographic evidence ACTUALLY shows.

This evidence supports the NIST contention that the building collapse progressed from the penthouse out as columns were weakened by the fires. The slow sinking of the penthouses, indicating the internal collapse of the building behind the visible north wall, took 8.2 seconds according to a NIST preliminary report. Seismograph trace of the collapse of WTC 7 indicates that parts of the building were hitting the ground for 18 seconds. This means the collapse took at least 18 seconds, of which only the last approximately 15 seconds are visible in videos: 8 seconds for the penthouses and 7 seconds for the north wall to come down.
