Former Congressional Office of Technology Assessment Senior Staff Member Calls for New Investigation of 9/11

By Alan Miller

In an online editorial yesterday, Joel S. Hirschhorn, PhD, former Senior Staff Member of the Congressional Office of Technology Assessment (OTA), called for a new investigation of 9/11. “First, let the technical truth emerge. Then, if necessary, cope with the inevitable political, conspiracy and other questions. But let us not allow a possible painful truth block the primary task of determining once and for all what caused the collapse of the WTC towers and building no. 7.”

Dr. Hirschhorn is a nationally recognized engineer who has testified before Congress more than 50 times on technology, science, and environmental issues. In addition to his work for the OTA, Dr. Hirschhorn also served as Director of Environment, Energy and Natural Resources for the National Governors Association.

Dr. Hirschhorn admitted to his own personal “growing skepticism about the official WTC story”. He wrote “analyses by many experts reveal the collapse of the three WTC buildings was not caused by the two airplanes exploding into the twin towers.” He noted “the general view is that the buildings were brought down by controlled demolition.”

Dr. Hirschhorn endorsed the efforts of a new group, Architects and Engineers for 9/11 Truth, to launch a new, honest and comprehensive investigation that considers all the evidence and which examines the possibility of controlled demolition.

Dr. Hirschhorn issued a challenge to supporters of the official account of 9/11, “If those that believe the official 9/11 story – especially elected officials – trust their views, then let them support a serious effort to test the validity of the controlled demolition hypothesis. If they fear and reject doing so, then let us see that as suspicious and unacceptable.”

He concluded, “Horrific possible answers can cause us to shun a question. But clearing our minds of the fear of painful truths is essential to clearing our nation of destructive lies. Otherwise, we stay stuck in a delusional democracy.”
