This is a square demolition. A plane would have messed up the grass directly in front of the building which it did not (not open for discussion). A plane would have gone through 3 rings of the building which MSNBC just reported... look at the picture below and previous pictures and you'll see the demolition only took out the first ring.
This obviously is a huge intel operation (hence random military witnesses and some non-military witnesses... none that saw both plane and explosion... many that saw one or the other) and they could get away with it fine if they just had more explosives to the left of the building to avoid the straight left wall which gives it away. If the left wall wasn't perfectly straight I would address the passengers but I don't even need to go there (you explain the left straight wall and I'll look into the passenger list. 
FWIW, I think the Mossad is blackmailing the US with stuff Deutch downloaded to his personal computer and the roque elements in the DIA/CIA and/or Mossad did the WTC and the Pentagon had a backup plan to avoid being framed... or to remove itself as a suspect (also to save its "allies" and credibility in the world)... they blew up the demolitions (probably plan z) and didn't do a good enough job with the demolotions... oh, another thing that gives it away is the Pentagon has security cameras all over the damn place!!! Duh.
This theory is not comforting but it is the only thing I can come up with that is realistic. Having said that I'm heading for comfort and leaving this thread. Regardless, Bush is a military/oil industrial complex whore!
