I had to jump in.
Let's look at this from another angle entirely. Let's assume that your allegation is true - That this video was doctored to appear that a plane had impacted WTC. If this is in fact true, then every single TV station that aired that footage is also complicit. This doctored footage would have to have been delivered to the television station(s) in the NYC area that were covering the event live. It would have been brought back to the Master Control area where the tape machines for on-air are kept. It doesn't end with the operator placing the tape into the machine and pressing play, either.
In order for this to have been pulled off, the Technical Director in the control room would have placed that tape machine on the on-air program source, with the various station CG ("live" keys, and such) superimposed over it. He/she would have used this tape rather than the usual tower-cam or helicopter shot, which if we follow the OP's allegations, would have showed a completely intact building.
This is ludicrous. I have worked in the TV business for a while now so I'm qualified to debunk this particular aspect of it. So - a shadowy NWO operative drops the tape off with instructions with what to do with it...no, no, that wouldn't work. It'd sit there on the receptionist's cart until someone from Engineering came down and got it. No, there would have been a team of armed "AGENTS WOO!!!" that would have stood directly behind the Master Control or Tape Operator as well as the Technical Director in the Production Control room and made sure they complied. In addition, these shadow operatives would have briefed the news director, producers, and on-air talent on what to say. I would make a call to WNBC's master control folks to see if anything like this happened back in 2001, but that would be insulting. You're more than welcome to do it if you wish.
This just points out the most likely scenario for this supposedly doctored footage making on the air and being presented as fact. I'm always 3 steps ahead of truthers so here's a couple counters to what I believe the retorts will be:
1. Maybe they shot the entire coverage beforehand and just aired the entire thing as if it were live.
Not possible. This would be conceivable had mass digital storage been utilized widely back then. How long was the coverage event? Several hours at LEAST. The capacity to store that video digitally and replay it on the air didn't really exist at the time, not unless they deleted all of their digitally stored local commercials/paid programs to make room. No TV station is going to do that - that's what generate their revenue. Ah, but maybe it was rolled off of tape! NO. Even today, the longest duration for a DigiBeta or Beta SP tape is about 80 minutes. These are the standard tape formats for TV stations. Even if they had recorded it on several tapes and rolled them out over the air, there would be a visible switch in the coverage as the Master Control router took one tape machine offline and put the other one on the air.
2. Mebbe they pirated the signal LOLZ!
No sir, I don't think so. There hasn't been an incident of broadcast signal intrusion since the Max Headroom incident in Chicago back in 1987...before that Captain Midnight managed to override the HBO uplink for a few minutes...that's it. The station would have used either a point-to-point studio to transmitter RF link, but most likely they're using fiberoptics to send their program signal to their transmitter - which would be located in an area outside of the greater city limits owing to RF hazards. Perhaps the NWO was able to somehow cut into the fiber cable between the studio and the transmitter and inject their doctored news footage with enough signal strength to override the actual TV signal, but you would have seen the line get cut at some point - the TV station would have gone dark for however long it took them to get their pirate signal on the line to the transmitter. I don't think that happened, Jeeves.
mchapman, if you would be so kind as to explain to me how it was that this doctored footage made it on the air?
Sorry this was so longwinded, but I think we're looking at game, set, and match here.
