ABOUT THAT SOUTH TOWER STRIKE

Next problem the east wall of the south tower! What's up with that? There's nothing moving in the correct direction, with enough force to take out all those box columns, and jet fuel only moves air at approximately 100 ft/second or ~90 mph. Hardly enough to take out windows designed to withstand 140 mph winds. You'd certainly think that any parts, with enough force to damage steel box columns would also be able to exit the building through the glass windows.  Yet, the only thing that comes out is a jet fuel fireball, which doesn't have enough force to even break the glass. So, without breaking through the glass, where does the oxygen come from,  for the fire to get hot enough to melt anything at all.

The upshot of which is to say that the east wall damage had to be the result of planted explosives.
