LC2E is far too speculative. I greatly dislike the style in which it casts suspicion on the passangers of the flights, or at least on the fact that they ever made phone calls. I think that its heavy emphasis on the Pentagon strike is most unfortunate. (For the record, I believe that all four flights, AA11, UA175, UA93 and almost certainly AA77 as well, were involved in the attacks, including impacts.) I do not contest the grievous factual errors in the third of the film that deals with the Pentagon, especially the following:
"the impact hole was 16 feet wide"
"9ft of concrete had to be penetrated"
"an A3 SkyWarrior hit the Pentagon"
"no or very little wreckage was found"
"blue tarp covered evidence"
"markings on grass could have been attack guidance"
