So my new boss, a former Navy man, was in the Pentagon when 9/11 happened. He has the stuff hanging on his office wall to prove his career and his time in the Pentagon at 9/11. He explained why so few died because the section of the building that got hit was under reconstruction. He said he was sitting at his desk working on budget cuts, and he felt the building shake, he looked out the window (he said they all face interior) and saw flying papers and smoke.
I forgot exactly how he mentioned it as part of the story, but he was friends with a Navy captain who said he saw the plane itself hit the building. I stopped him in the middle of his story, and confirmed this, and we both referenced the only video. At this point, he let me know how much he argues with his cousin the conspiracy theorist, about 9/11.
Now, this is just one data point, and even more so it's second hand. But he trusted his friend and coworker who said he literally saw the plane hit the building with his own two eyes. Given the context of the conversation, and who this man is, my boss isn't lying. It is possible he was lied to, or the captain was mistaken, or even a missile was disguised as a plane.
Just thought I would share. I'd give more information, but I don't want to be doxxed. It's not to often you meet people on the scene, so to speak.
I thought all the windows faced inwards. Kind of hard to see a plane skim just above the ground, low enough to fly under power lines, impact the outside of the Pentagon with no window facing that direction. One would assume seeing a plane shaped a cruise missle would be quite memorable to leave a perfectly round hole with no wing impact evidence, fly below the powerline without clipping one wire and leave no debris. Then again if I saw a plane that did that I’d remember it too. That’s it story validated.
