This video was posted in an earlier thread which no longer accepts replies, so I'm reposting it here. And this deserves to be highlighted, because an anon said the video doesn't necessarily prove anything because it could have been shot from any angle, and I'm going to prove exactly what angle it was shot from and how it shows beyond any doubt that no plane actually hit.
The two WTC towers were arranged in a staggered pattern. That is, Tower 2 was located to the south and east of Tower 1. In the video, we see the towers almost directly ahead of us. The tower on the left is farther away and the tower on the right is closer. Because of the locations of the towers in relation to each other, that means the video could only have been shot from two locations: from the north looking south or from the south looking north. If the video had been shot from the east looking west or from the west looking east, in both cases whichever tower appears on the left would be closer and the tower on the right would be farther away, the reverse of what we see in the video.
If the video was shot from the north, the farther tower on the left must be Tower 2 and the closer tower on the right must be Tower 1. If shot from the south, the farther tower on the left is Tower 1 and the closer tower on the right is Tower 2.
We all know that Tower 1 was the first hit, and that it was supposedly hit on its northern face near the top by a plane traveling north to south. We also know that Tower 2 was hit later on its southern face about two thirds of the way up by a plane traveling from south to north.
If the closer tower on the right is Tower 1, and we are looking at its northern face, and the explosion we see in the video comes from a plane hitting it that is blocked from our view by the tower itself, this would mean that Tower 1 was hit a second time from the south after being hit the first time from the north. And we know this simply isn't true, that it was hit once from the north and near the top.
Since this is ruled out, it means that this video was shot from south of the towers looking north, and that the farther tower on the left is in fact Tower 1 and the closer tower on the right is Tower 2. So in this video, the explosion we see happens on the southern face of Tower 2, precisely where the second plane supposedly hit it. This cannot be disputed. AND THERE IS NO PLANE IN THE VIDEO. There is only an internal explosion, blowing outwards.
