It just sounds fishy to me. Terrorists with box cutters were able to penetrate the best air defense in the world? And fly planes perfectly? You can even see a missile fly out from under the plane in one of the videos. Those were not commercial planes. They were military. You can clearly see it in the video.

I hate to say this, but most Islamic-associated terrorism is very badly planned, by individuals, using only knowledge about how to build bombs, off Google. However, 911 appears to be an outlier, that was planned very well, with a few dollars behind it. Osama decided not to do any more hits on America, because it did not achieve any objectives. Basically, it just pisses Americans off, and they would be more likely to nuke Iraq or Syria. They did however, continue bombing European targets, and got some strategic results, with some countries like Spain moving out of alliances.
The reason I hate to say it, is 99% of Islamic-associated terrorism is very badly done, using suicide bombers, against soft targets. Timothy McVeigh is someone who put a liddle bit more effort into his project, and the results were quite significant, even compared to 911. In Australia, a kid opened a telco fibre pit in the ground, and put something burning in it, and wiped out internet on the north east coast of Australia. The thing we don't like to think about, is that we are terribly vulnerable to anyone who has a brain and wants to do some damage. If someone who was better educated wanted to wage war with your country, it would be unpleasant, and the cops wouldn't catch them. We have built a house of cards.

I think you seriously misunderstand the limits of frame by frame video analysis. In that era, INTERLACE was dominant. Interlace is a way of perceptually fudging extra frames and lines into the display. It fools the human "eye" and brain into believing that there is more information there, than there really is. But it's horrendous at displaying movement. When interlace is converted to modern "progressive" systems, there is no clean method to do it. Successive frames end up being merged in garbled ways, depending on the particular deinterlace system the editor just happens to pick. When I deinterlace videos, using AviDemux, I just pick a random field merge system, out of about 5 that it lets me use, and hope for the best. I have no real idea what fudgy result I'm going to get.
Here is a site showing what interlace artefacts look like. At the bottom is a photo he asserts is deinterlace properly. It's only proper because his eye says it looks right, and he got away with it.http://www.100fps.com/index.htm#whatis
Also, think about why some government conspirator would bother putting missiles onto a plane. Surely, slamming 2 planes into the buildings was bad enough? PCT also assert that the inside of the building were rigged up with explosives.
MAKE UP YOUR MIND AND STICK TO ONE STORY, MORONS.
