Well if it looks like a duck and walks like a duck. However which aircraft would have been able to punch through all 3 walls of the pentagon, if any? Would any aircraft have been able to? And if not, what does that mean? Planted explosives?
According to the argument, the object that produced the hole had to travel through five masonry walls: The facade and inward-facing wall of the E-ring, two walls of the D-ring, and two walls of the C-ring. That would seem to be too much material for any component from a passenger jet to penetrate.
This argument is based on a misunderstanding of the Pentagon's design. In fact, the light wells between the C- and D-ring and D- and E-ring are only three stories deep. The first and second stories span the distance between the Pentagon's facade and the punctured C-ring wall, which faces a ground-level courtyard. There are no masonry walls in this space, only load-bearing columns. Thus it would be possible for an aircraft part that breached the facade to travel through this area on the ground floor, miss the columns, and puncture the C-ring wall without having encountering anything more than unsubstantial gypsum walls and furniture in-between.
Lets be honest, there is absolutely no evidence that a Boeing hit the Pentagon.I wouldn't go nearly that far, there's actually quite a bit of evidence that a Boeing hit the pentagon. Check this thread out.
But that doesn't exclude the possibility that a smaller aircraft or missile did.
There are believable reports that some sort of aircraft flew into or over the Pentagon.I've heard of no such reports.
