I do believe it was a very strange event . . . While I voted for an inside job . . . I would not be surprised if something else was the ultimate explanation. the two things I am sure are:
1). There were hotspots under all three buildings which cannot be explained by any theory of kinetic energy or combustibles burning for weeks . . . I have no theory to cover this fact.
2). The melting of aluminum Block engines around ground zero . . . While no person to my knowledge was turned into a human torch . . . All you have to do is go to ancient Pompeii to know that that is nonsense. I also have no theory to cover this set of facts.
