If someone walks me through the process, I'll post some picture that have been cleared for release.
Let's look at some of these questions from a different perspective. Picture in your mind the number of press reports, pictures, and videos we've all seen about WTC. Now contrast that to what you've seen from the Pentagon (hint, there should be a big difference favoring WTC). OK, why? Conspiracy - NOT! Maybe it's to protect the classified information that littered the attack site, and to protect the identities of many law enforcers who were brought into the restricted site to help investigate the attack???
The offices in the Pentagon handle the Nation's military secrets, be they paper or electronic based. When a plane weighing over 800,000 pounds and moving in excess of 350mph slams into a solid object, the blast effect is enormous - - add the fact that 60,000lbs of fuel spilled out, followed the plane's inertia path 200 feet through the building, vaporized along the way, then ignited a split second later, I hope you can see the intensity and enormity of the overall blast effect.
You also have to know how the building is configured to put this together to get a clear picture. The Pentagon is not a solid building. The five rings that make up the unique design all have their own inner and outer walls, then clear and open areas between the rings before you reach the next wall of the next ring. There are corridors that run from the inside A ring to the outside E ring, with the corridors being connected by perpendicular hallways (I know this is hard to envision. Maybe I'll see if I can post a picture that shows this, or look at previous posts that show the overhead and you can get the idea).
So, the blast effect over a width of 500+ feet, to a depth of over 200+ feet, and five stories high, created an enormous evidence field when classified information was dislodged and began to float around in the fires, and in the water from the broken pipes, etc., as well as having been blown into the open areas between the rings, and through the hallways and corridors. It all added up to one big security problem, hence no pictures released that could potentially show a military secret that would aid an enemy.
A similar situation potentially existed with the sheer numbers of law enforcement folks who flooded the crime scene. Military and civilian agents from every three letter abbreviation you could imagine, all the way down to the EPA (due to the hazardous materials released - - NO, not another conspiracy here, but PCBs and the like from all the electrical vaults and blown transformers, asbestos, etc.)came to assist in the investigation. I can see where some agents would like to have their identities protected, thus NO PICTURES. It's not to hide anything, it's to protect people so they can live to fight another day.
Look closely at the motion of the stills from the security camera (thread 194). As I previously stated, you can see the blur of the aircraft in the contrast between frames 1 and 2. The lens was never designed to show the depth of field needed to render any clearer a picture. Look at the rest of the frames over and over again and you'll see aircraft parts and debris being showered to the front of the building and over the top of the E-Ring.
I was an eye witness to the fact that it was an airliner that struck the building. The cockpit and front landing gear strut and tire assembly (wreckage) ended up 240 feet into the building coming to rest on the outside wall of our offices. We were in the office that day and we exited into A&E drive to find the building on fire, and people needing rescue. We did just that, and in the course of those rescue efforts, we directly observed hundreds of pieces of what was the American Airliner.
I guess it takes a lot of paper clips hanging off your belt (in a single trail akin to an antenna) to apply some reason to the madness.
