Your comparism of a ping pong ball going through a paddle is your evidence? Ive seen straw go well into telephone poles, i have seen plywood go thru and into buildings. Yet i see no proof where a plane can cut into steel structure and concrete all the while maintaining its structural shape, then have the nose cone travel completley thru the entire structure completley intact. The nose cone looks more like the front of the bunker buster bomb i posted to you. You have offered no proof of evidence to the contrary.
