"I am probably preaching to the choir here, but the reason that flight 93 remains are stored in an Iron Mountain is because they display evidence inconsistent with a plane that simply nose dived into the ground. Let us not forget that wreckage was strewn for 6 miles, which is what you would expect to find when a plane is shot down with a missile at 30 thousand feet. The wreckage of a nose dive would be contained to a relatively small area. What about WTC 7???"
