Mathematicians for 9/11 Truth
Developed open-source software calculating WTC tower collapse velocities at 6.5 m/s² - matching controlled demolition profiles. Current research: 3D modeling of debris dispersion patterns inconsistent with pancake collapse theory.
Founding Story
Founded in 2009 by Purdue professor J. Leroy Hulsey to counter NIST's computational models:cite[5]:cite[8].
Founders
J. Leroy Hulsey (structural dynamics expert), Tony Szamboti (mechanical engineer), and Crockett Grabbe (plasma physicist).
Credibility
2024 University of Alaska validation of collapse models. Cited in 2025 Senate Homeland Security hearings:cite[5]:cite[8].
Truth Movement Organizations
In the aftermath of the 9/11 attack, dozens of Truth
organizations and groups were founded. This page provides an overview of some of these organizations.
