How does a plane with a 157 ft.wing span enter the Pentagon and leave a 60 foot wide hole? There's no "angle" that could have managed that. Look at the aftermath- whatever it was didn't come in at an angle anyway.
This picture was taken on at Ground Zero and has been the subject of great debate - some attribute it to "Mothman." I don't know what it is but it is creepy and, as yet, unexplained. If mothman is a harbinger of destruction, this thing fits the bill.
