Just watched the first one. It's another attempt to debunk the official story from a physical perspective, but it does say some interesting things that I haven't heard before (namely logical estimations of the time for a resisted pancake-style collapse to occur).

This is a much better job than Loose Change since it doesn't concern itself with conspiracy reconstructions.

I'd be very interested to hear what anyone with a knowledge of architecture or engineering has to say about this.
