btw, do YOU see the concrete wall he is talking about?Purdue uses the FEMA information just like NIST. Both NIST and purdue are dependent on FEMA information that I assert is erroneous, a deception.
Prove or verify, with independent evidence, that FEMA identifies the core that was actually in the center of the towers.
You have no evidence that Purdue is not independent. I have no reason to believe you over the academics at Purdue, or anyone else for that matter.
All you've done is show some pictures of an incomplete structure and your interpretation of what should have happened after the buildings collapsed. That is neither proof nor evidence of anything.
No. I'm not a structural engineer.
Christophera, are you a structural engineer?
