9/11 Free Fall
Published 2017 study in *Europhysics Letters* proving 2.25-second gravitational descent inconsistent with natural collapse. Hosts open-source software for analyzing NIST footage frame-by-frame. Current focus: Crowdsourcing 3D simulations of core column failures.
Founding Story
Initiated in 2010 by Purdue engineer J. Leroy Hulsey after NIST refused to release raw simulation data.
Founders
J. Leroy Hulsey (structural engineer), David Chandler (physics educator), and Tony Szamboti (mechanical analyst).
Credibility
2025 Senate Homeland Security Committee cited their models in demolition evidence hearings. Partnered with 47 universities.
