WTC7 seems to be a classic controlled demolition. WTC 1 &2 destruction appears to have been enhanced by thermate (a variation of thermite) in addition.
Pentagon was not struck by a passenger aircraft. It was a drone or missle.

Bloglines - DID THE PALESTINIANS REALLY DIG A TUNNEL UNDER THE NOSES OF THE ISRAELIS?
As an engineer I've given the notion of digging a tunnel which the Israeli Ministry of Foreign Affairs tells us was some 650 metres long, dug under sand across the Gaza border into Israel some thought. I'm beginning to wonder whether this is actually feasible especially considering that it would have to be built covertly and across the terrain that Israel claims. A 650 metre long covert tunnel being constructed under sand is a considerable undertaking the logistics of which would be enormous. The tunnel, even a crawl tunnel measuring 900mm x 900mm in cross section, would require 100% full shoring if actually constructed in sand and at least 60% if constructed in clay/soil. That means all that shoring material, literally tonnes of it, would have to be loaded down the shaft of the tunnel head and then transported along the tunnel to the tunnel face where one man at the face would have to position it and then excavate out the next section of tunnel with all the problems that that involves in shifting the excavated material back down the tunnel to the head shaft where it would have to be disposed of. Rock would be out of the question because of the noise of hammering through it and the extra logistics of getting hammer equipment to the face.
