This video was supposedly shot entirely by a Czech immigrant named Pavel Hlava. It surfaced in 2003, and was broadcast September 11th, 2003 on ABC's Good Morning America TV show, never to be aired again! The New York Times also published an image from this video. (download)
Above is the complete ABC TV presentation, all 1 minute and 22 seconds, of the Pavel Hlava video as seen on Good Morning America.
Note that, in the first of Hlava's shots, the blue sky is filled with green analog tape noise, but in later shots the visual noise in the blue sky is much less, and mostly red.
Also note the prominent bulge in the belly of that thing, about which we are left to wonder...
We're sorry we do not have a crisper view of this video. We are left to speculate whyNASA has never enhanced any of the 9/11 videos...
The best we can do is show you what a 767 is supposed to look like - remember that a 767-322 is 20 feet (6 m) longer than the 767-222 that departed Boston as Flight 175 (...we don't know for sure what hit the towers: no flight data recorders ... no cockpit voice recordings ... no ground RADAR data ... noACARS data...).
The first 3 links are to images of the actual registered aircraft which took off on 9/11 as Flight 175, and the remainder are to other images of 767s:
