Columns are appoximately 10ft apart center to center.
Columns 15 and 16 may have been damaged, but they surely were not missing. The wing of a 757 could not have fit through that small gap in the broken column.

This should be column 11A in the report above. Which says it is missing?
The angle of this picture is simlar to the trajectory the "plane" took. So then why is this column pushed to the right. Surely, the force of the wing, or wing root, which is the strongest part of the plane, should have bent this structure to the left?
