Pentagon Plane, page-485

Don't take my word for it dopey, listen to the experts.

According to Dusenberry and his team’s analysis, the lightweight wings and non-fuel sections of the plane sheared off almost immediately upon impact, but the heavy fuel tanks barreled through the first floor, creating a flow of debris that tore through the building like an avalanche, leaving a path of destruction twice the length of the aircraft.Dusenberry compares the Boeing 757 aircraft to a water balloon.“The balloon itself is not very strong, but if you fill it up with water and you throw it at something, it hits and exerts a fairly high force,” says Dusenberry. “It’s that moving mass that needs to be stopped by the object it strikes that results in the generation of force.”
