Sept. 5, 2007 - 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."
