Whatever it was, it's NOT a Plane

There is no flightpath anywhere evident in the whatzit frames, except something moving at incredible speed moving in from a 1:00 position, and moving faster than the explosion cloud can later unfold. -- That's FAST.

From the point this object is visable until it passes in front of the building is only a second and a half in real time. The eye cannot follow this, but by supreme blessing, video can.

Video is nearly 30 frames a second, and I do want to remind you this scene was photographed with the best of video equipment by a professional film crew. It was not "fuzzied up" for public consumption either -- notice how evenly Harvey's image is fuzzed.

In the whatzit images, the apparent undulation of the building is uneven, and varies from frame to frame. There is a halo effect around the south tower. The object approaches from 1:00, crosses the face of the building, makes a flash, and then creates what I discribe as dust pimples, each of which explodes individually. There is no frame that looks even vaguely like the History Channel's recreation of the event:

here is their approach shot, fuzzed up with photoshop, for harvey's amusement.. I had to hit the "blur more" setting fifteen times to achieve this level of "fuzzyness."

In the actual frames of the Fireman Video, there is no similar effect. The frames that appear to be planelike are out of sequence with the notion of a plane: Planes do not grow from dust pimples. They just don't.
