I studied TV Video Fakery for two years, and eventually threw it into the garbage can, embarrassed that it took me that long to debunk it.
TV Fakery says everyone who says they saw a plane in the sky that day are liars, and I just could never bring myself to do that. Too many people, friends and strangers alike, have told me that they saw (what they thought was) an airplane in the sky for me to call them all liars.
My friend stood on a rooftop at Montclair College in New Jersey, and said she saw the plane. I quizzed her backwards and forwards, probably annoying her, but she said absolutely that she did see the plane from the top of the roof.
A young colleague of mine said he saw it from out his window when he was in high school in Brooklyn. The man seemed to be transported back in time when I questioned him closely about it. He insisted that he, yes, saw a plane out of an open window in Brooklyn.
If the fake plane was a magic trick, it all fits. Eyewitness testimony, video and still photography, lack of a plane crash. It all fits.
A real plane doesn't fit because there was no plane crash and because planes can't do that to buildings, anyway.
A "faked video CGI-inserted" plane doesn't fit because of all the eyewitness testimony and videographic evidence.
A fake plane fits ALL the data, which is why I think it happened.
Explain how they faked a plane crash in front of hundreds of thousands of witnesses and hundreds of cameras without anybody from any angle noticing. If you cannot do this, there is no reason for any sane person to even consider your "magic trick" nonsense.
