I personally know one of those on the team who went into the Pentagon, recovered the bodies of those on that flight, and positively identified all the passengers and crew on that plane. The found not only the remains of all passengers and crew, but also many personal effects, luggage and things they brought aboard the plane. Painful stuff sometimes to see, children toys and so forth. These were dedicated people driven to do what they could to provide the families of the victims some closure. They do not deserve to be smeared by hateful conspiracy theorists.
The supposedly small hole in the Pentagon you refer to is one of the biggest bullshit stories ever. The hole on the outside of the Pentagon was filled when the upper floors of the Pentagon collapsed into it and was wider the the length of the fuselage. The wings lacked sufficient strength to penetrate the building, only fuselage did. The hole associated with a certain well known picture was well inside the Pentagon (in the C-ring) and was from a small piece of the plane (some landing gear) that managed to get that far. That’s what drives me crazy about conspiracy theorists, they peddle openly dishonest bullshit like this as truth.
Please provide your engineering, or other relevant credentials, justifying your claim that the “damage caused could not have caused a symmetrical collapse.” I ask because this unsupported conclusion, presented by you as if it is indisputable fact, is in fact disputed by every reputable engineering organization that looked at this issue including the American Society of Civil Engineers and the New York State equivalent.
This stuff gets dismissed as idiot conspiracy theory quickly because it is factually wrong, made up tripe, and because it ignores any evidence contrary to the conspiracy theory.
