I wrote the following article for my own blog 11 May last year- www.truxtop.blogspot.com. Like most people, the whole 911 episode was so overwhelming that it took awhile for the shock to wear off, but a couple of things bothered me. Mostly I thought about the Pentagon and the fact that there was little or no mention of the passengers, no lists, no group of parents/family members of the passengers, as there are in the WTC and Pennsylvania crashes.
Another item about the plane crashes was there was seemingly no reconstruction, no report about the airplane itself as is usually the case in airliner crahses where they assemble the pieces in a warehouse somewhere. Also, it seemed to be pretty damned good flying for "student pilots".

I am new to this site, so perhaps I will find more information about those two items here.

Since my firm was in the business of staffing high-level engineering and construction professionals, we had a good idea of which firms were getting which contracts, and knew that a contract had been let for renovations to the Pentagon. It turns out that being able to hit the Pentagon where they hit the Pentagon was more than luck.

I admit to thinking that there was something unsettling about the whole American Airlines Flight 77 into the Pentagon aftermath. It appeared that there was not enough wreckage of either the 767 or the building. It made that particular aspect of the 9/11 trauma ripe for speculation as to what happened to the plane. Why wasnt there more damage to the building? Did a plane actually crash? Was it a hoax?

I believe it was a plane crash and it was the wreckage of flight 77, which puts that particular conspiracy to bed, but it brings up another poser.

It seems that the Pentagon is undergoing an upgrade, according to an engineer at Amec Engineering, which had the contract to strengthen the Pentagon against attacks, to make it nearly blastproof. The construction was being done in phases.

Flight 77 struck the only portion of the building that had already been renovated!

It was the only area of the Pentagon with a sprinkler system, and it had been reconstructed with a web of steel columns and bars to withstand bomb blasts. The steel reinforcement, bolted together to form a continuous structure through all of the Pentagon's five floors, kept that section of the building from collapsing for 30 minutes--enough time for hundreds of people to crawl out to safety.

The area struck by the plane also had blast-resistant windows--2 inches thick and 2,500 pounds each--that stayed intact during the crash and fire. It had fire doors that opened automatically and newly-built exits that allowed people to get out.

So it seems the "terrorists" hit the Pentagon precisely, in an airplane with perhaps a 300-foot wingspan, within a 900-foot wide zone that comprised the only section of the vast complex that had been completed at that point.

Most of the wreckage, except for the heavier engine assemblies, simply disintegrated, like an airplane hitting a big rock. This is too much coincidence for any rational person. I hope this adds to the discussion.
