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.
