Cock Pit Door Not Closed

I'm not trying to give anyone false hope. I'm just trying to find someway to "prove" the Flight 93 crashed.  There is no evidence.  There "may" be evidence of "remains planted in the field" but there are NO conclusive reports that a passenger plane crashed in Shanksville.  Furthermore, the 9/11 Report says the Passengers voices were recorded on the "Cockpit Voice Recorder" as they planned to "Force The Door" and crash the plane.
