has this been outed before on wtcdemolition/footage discrepancies and black outs?

I think there is a possibility that some broadcast footage was tinkered with but I am convinced that large planes hit the towers.

It's interesting to trace the history of the "no planes" meme in the Truth movement. At the point when I became involved, "no planes" meant no planes at the WTC and was inextricably bound up with heavy duty psy-ops drama -- ie, the nuts who very theatrically pushed the idea versus the "responsible truthers" who generated tons of "credibility capital" by opposing them and playing their victims. Prior to this chapter, however, "no planer" was a derogatory term used to dismiss and belittle the vast majority of sensible truthers who looked at the Pentagon and saw no plane! (Most vociferously, of course, by at least one person who is utterly transparent about his desire to keep Arab/Muslim hijackers at the center of the narrative.) Now we've come full circle: the "no planer" label is again mostly applied to critics of the Pentagon/Flight 77 story, AND it now carries infinitely more psy-optical weight thanks to its detour into NYC crazy people land.

is that disinformation artists often exploit strange-looking phenomena that could have more than one explanation. The "no-planers" often pretend to be video experts in analyzing the video footage of the WTC attacks, yet when you talk to real actual video experts, you discover that there are other explanations for much of what the blatant disinfo artists (Web Fairy, Gerard Holmgren, Nico Haput, etc.) make out to be "video fakery" or "holograms". For example, there is a phenomena known as "video artifacts" that can occur with digitized video of poor resolution with fast moving objects. Much of the video of the planes impacting the WTC towers are wide shots from far away with poor resolution. You really can't rely on such poor quality video to prove much of anything as far as what the planes actually looked like right at the point of impact. For instance, what at first appears as though the wings disappeared just before impact, can easily be explained with the digitized frames not being able to capture enough information to keep up with the speed of the crumpling/piercing of the plane with the side of the building and so the digital video "averages" the colors and shapes into what looks like ghost wings that disappear just as the plane contacts the building.

The point is to always ask yourself, "are there other possible explanations for what seems strange at first on a low resolution zoomed video of fast moving objects?" Since the tactic of exploiting low resolution video/photos has been used by disinfo artists so often in the past to insert disinformation - remember the pod and flash nonsense? - that is one thing we need to be extremely skeptical about and make sure that better explanations are not being overlooked.

A more interesting line of inquiry regarding the aircraft that were used in the WTC attack is being done by Pilots for 9/11 Truth. Their new video that was recently released, called 9/11: WORLD TRADE CENTER ATTACK, discusses the fact that the reported speeds of most of the planes on 9/11 at the time of impacts are extremely unlikely because the alleged speeds are too fast for regular commercial airliners at sea level without the planes loosing control and/or potentially breaking up. P4T do NOT endorse a "no-planes" explanation for this, despite what the fakes who try to endlessly discredit P4T falsely claim. According to P4T, the improbable speeds point to either 1) the reported speeds are incorrect or 2) the planes used in the attacks were modified Boeing aircraft or other military aircraft that can sustain faster speeds. This, I think, is a very interesting path of research and may go a long way in helping to expose whether the alleged commercial flights were real or not (and, by extension, whether some of the alleged airline passenger victims were faked). Obviously, this is very "dangerous" possible truths for the perps, which is why the fakes like Jim Hoffman, Victoria, Arabesque, Jon Gold, John A, etc., must work overtime to discredit organizations like P4T.

Edit:The black outs are something that might point to some shenanigans, such as the perps wanting to mask simultaneous explosions occurring in the first tower while the plane hits the second tower, or, who knows. But, too many people have independently verified that planes hit the towers for me to accept "no planes" as a possibility.

I've never looked into this whole tv fakery thing in any depth but there is one nagging question that I remember having which I've never had answered: If I remember correctly, aren't there some videos of the plane coming in straight and level while others show a steep last moment descent? Hopefully someone more familiar with this info/disinfo than I can point me to an answer.
