WTC South Tower enrty. Flight 175 (enlargement here)
Floor Spacing, and what seems to me an unidentified structure problem
( this structure problem was present in closeups before the plane hit )
The fuselage may well have entered only hitting one or two outer support beams,
not hitting the floor structure itself, and possibally missing any major support columbs or elevator shafts. The fuselage is like a long hollow tube piercing through, where as the wings would have been sheared off by hitting at least one, or probabally 2-3 floors. The floors present more resistance being that they are a continuous structure.
Just before the plane hits, It looks like something is in front of it?
It is possible that this is a peculiarity
in the process of saving the image from a video frame.
This is a frame from the video of something exiting the building.
How could the nose, or front part of the main fuselage survive intact
all the way through the building?
Engine diameter. 9 ft. 6 in Engine length 11 ft 6 in
What exited had a rounded front, and was longer than 11ft.
