anyone have an explanation as to why it would be altered?
No, Perry is 100% spot on. There is ample evidence that it wasnt tampered with by using simple logic and reasoning skills. This evidence of tampering might make sense if:
- there was anything visible that looked like an airliner, just before impact. Or...
- the alleged tampering was only evident in the the timespan of the event above, which would be no more than a split second - and not throughout the feed.
Water bender, if you were in charge of doctoring a tape to cover up foul play. Would you:
- Just doctor up the 5 or so frames(assuming the video is 5 fps) that clearly show your cruise missile/Global Hawk.
- Doctor up the whole tape, including peoples movements minutes afterward for absolutely no reason whatsoever?
Considering the low quality of the feed, you have no idea how easy it would be to simply "erase" the missile/Global Hawk/UFO in just 3-4 frames of the video(and even insert a properly shaded blur of an airliner). Its just silly to think they edited many parts of the video for no reason whatsoever.
