Ronald Pordy Video - "Another CNN Gem"
You can see from the image set below that both the port and starboard wings of the UA175 aircraft
are experiencing just as much deformation as each other (if any at all) and that the dihedral angle of
the wings is identical to the dihedral angle of the wings on the CG model.
The image used here was taken at roughly the time as the previous Anthony Cotsifas image.
There is no port wing deformation due to the effect of a pull out from a high speed dive while being
banked to the left.
The UA175 aircraft's attitude and trajectory are acceptable while the airframe is an almost perfect
match for the CG model except for a slightly different fuselage length and
a misplaced port engine nacelle. The CG model does not take into account the
shadowy area cast by the WTC1 smoke cloud.
Just like the CNN Best Angle video there appears to be an abnormal amount of compression artefacts around the airframe relative to other objects in the captured image, which is surprising given the relatively high resolution of the video.
Incidentally, NIST reported in their 2005 investigation of the WTC attacks that...
"The wings of the aircraft were also deflected from the surface model
geometry to represent their in-flight condition… A cubic function of
the wing span was used with a tip deflection of approximately 52 in.
Tip deflection was estimated from the impact pattern seen in the
photographs of the WTC towers and from damage documented on the
exterior panels by NIST."
(Analysis of Aircraft Impacts into the Word Trade Center Towers, NIST NCSTAR 1-2B, Section 4.3)
Perhaps if NIST had used the Ronald Pordy video to ascertain wing tip deflection
they might have noticed there wasn't any.
