Flight 175.
The same still through 11 filters


"The same analysis has been performed on various images. The selected images are fragments of photographs of the attack on 11 September and a Boeing 767-300.

"The studied images are taken from different angles of observation.

"The detected cylindrical objects cannot be due to shadows caused by the angle of incidence of the sun on the plane, because they always appear to be the same shape and size, though with varying luminosity.

"The detected objects have varying luminosity around them because they are in relief (this is the only possible explanation).

"The detected objects are clearly distinct from the landing gear."
