"Sadly for the conspiracy theorists, the entry point is clearly shown, and on each side of the otherwise parallel lines of the 'passage', is a 'triangle' where the building crumbled as the wings hit it."

Give it another look. The plane hit at about a 30 degree angle. Shouldn't have been a triangle there at all.

Angle here. See line in grass. BTW, that pic is from 4 days prior to the 'crash'

You can suggest no one else knows how to look. But many of us do know how to see.
