the "damaged spool" is not a recognizable spool at all

The image in impact is much brighter than any of the other 4 images. The brightness is higher throughout the image, not just in regions that would be illuminated by the bright explosion. There is no evidence of shadows from the explosion that is supposedly the source of the heightened brightness. Note the setback in the facade in the middle of the images to the right. The setback is considerably closer than the explosion, yet it casts no shadow on the portion of the facade just in front of it. There is also an absence of any evidence of even faint shadows from other objects, such as the structures in the vicinity of the camera. The sky is also brighter and a different hue, as if an explosion could brighten a clear sky.

The last three frames show an explosion with a shape that is roughly axially symmetric around a vertical axis. The center of the impact zone lies approximately behind the center of the helicopter control tower. That places the central axis of the explosion well inside of the building -- easily 100 feet behind the facade. But the part of the building above the impact hole did not collapse until well after the impact and explosion. How could an explosion evolve in such a symmetrical manner around the obstacle of the building without reflecting the shape of the building? The only plausible explanation is that the explosion imagery was superimposed on the building through image manipulation.

By the last of the five frames, the explosion, which appears to extend to at least four times the building's height, has become dark with soot. Yet the huge explosion casts no shadow from the sun on the lawn below it. Shadows of other objects show that the sun is low in the southeast, as one would expect at 9:40 AM in September. The Pentagon's wall, which faces almost due west, casts long shadows extending to the left and toward the camera. But there is sunlight-illuminated lawn directly left of the huge explosion. The uppermost swath of white in the enlargement to the right is part of the heliport, which was directly under portions of the explosion. Yet it is illuminated by direct sunlight.
