Here is what took down WTC:
1) The moment one of the planes hit one of the towers, debris from the impact hit WTC 7 hit the building, did a small amount of damage, and caused fires.
2) When one tower fell, it was like an earthquake.
3) When the second tower fell, it was like another earthquake.
4) When one of the towers fell, debris hit the WTC 7. It did so much more than "hit" the building - It pretty much buried the lower floors. You could not leave WTC 7 because the exit was covered with debris.
5) When the towers fell, it did a lot of damage to one side of WTC7, which destroyed the support of the upper floors.
6) The fires continued for hours, which eventually did the building in.

The video you see is of the far side of the building which looks completely undamaged. It's very misleading.
