Re: Another interesting question is the calculated G-forces on both the Pentagon and WTC attacks... anybody know the calcs on those? What is it you are looking for here? The impact force? Right after 9/11, there were some interesting facts presented on the FADG thread regarding airliner footprints and the likely penetration of same on a nuclear reactor containment. The fuselage basically crumples, and the only part of an airliner that achieves any penetration of the reinforced concrete shells is the engine rotor, which weights about 12,000 lbs. This however is not capable of penetrating the typical 4.5 feet of thickness of the typical containment structure. The type of damage on the Pentagon is as you suggest. Completely consistent with damage to be expected from a projectile with a dense nose cone, and completely inconsistent with the damage to be expected from the two engine rotors of a 757 with the fuselage and midsection basically achieving little penetrative force.
