Explain why he would be expert in this! 9/11 Conspiracy Theories | Debunking Pentagon Plane Crash Myths (popularmechanics.com) "Why wasn’t the hole as wide as a 757’s nearly 125-foot wingspan? A crashing jet doesn’t punch a cartoon-like outline of itself into a reinforced concrete building, says ASCE team member Mete Sozen, a professor of structural engineering at Purdue University." "In this case, one wing hit the ground; the other was sheared off by the force of the impact with the Pentagon’s load-bearing columns, explains Sozen, who specializes in the behavior of concrete buildings. What was left of the plane flowed into the structure in a state closer to a liquid than a solid mass. “If you expected the entire wing to cut into the building,” Sozen tells Popular Mechanics, “it didn’t happen.”" "Blast expert Allyn E. Kilsheimer was the first structural engineer to arrive at the Pentagon after the crash and helped coordinate the emergency response. “It was absolutely a plane, and I’ll tell you why,” says Kilsheimer, CEO of KCE Structural Engineers PC in Washington, D.C. “I saw the marks of the plane wing on the face of the building. I picked up parts of the plane with the airline markings on them. I held in my hand the tail section of the plane, and I found the black box.” Kilsheimer’s eyewitness account is backed up by photos of plane wreckage inside and outside the building. Kilsheimer adds: “I held parts of uniforms from crew members in my hands, including body parts. Okay?”" That's 2 structural engineers telling you it was a plane and I put it to you that they know more than some pilot! @Scott - Are you gonna answer this!? @Scott - Are you gonna answer this!? @Scott - Are you gonna answer this!?
