Flight 77 struck the west side of the Pentagon at the 1st Floor level just inside Wedge 1 near the 4th Corridor and proceeded diagonally at an 60 approximate 42 deg angle toward the 5th Corridor in the mostly vacant Wedge 2.
If that was the case, then this part of the building and its still intact furniture, would have been at the very least charred if fnot destroyed
The chain of destruction resulted in parts of the plane ending up inside the Pentagon in reverse of the order they had entered it, with the tail-end of the airliner penetrating the greatest distance into the building.
There was no evidence of a tail or any other major parts
