DESCRIPTION: This is a still from Jamie's CNN video. This is the piece that he suggested may be a cockpit window. The research I did on cockpit glass brought me to the conclusion that it is much thicker and layered than this piece.

This is typical airliner cockpit glass. It is from a Boeing 737 after it was struck by a bird. It appears to be substantially thicker and seems to have a different breakage pattern than the piece on the lawn. Notice how the piece at the top of the page is folded over on itself.

The above diagram shows the construction of a Boeing 757 cockpit windshield.

Here is a window that was partially broken right in the area where Jamie's video was shot. All of the windows to the left of this have been blown completely out. You can see the similar breakage pattern to the original piece on the lawn. In the top right image you can see another piece of glass. In the bottom right photo you can see yet another piece in proximity to Venetian blinds. I believe the glass on the lawn is from the first floor windows.

This helps locate the photo directly above this one. You can see the labeled window on the right. The grass in the left foreground of this photo is the area that the video of the broken glass was shot. It is right in front of the blown out windows. If you look at the windows you can see that whatever blast force blew them out came from the inside. Notice how everything is pushed forward against the window frames and the debris has been projected out from the building.
