Dr Judy Wood is not the only scientist speaking up about exotic weaponry at the WTC:

Dr Jeff King, MD, former M.I.T. Electrical Engineer, was one of the first to speak up about controlled demolitions at the WTC. The previous link is from 2004, but much evidence has come out since. Listen to this MP3 from Webster Griffin Tarpley's March 2006 radio show, where he discusses exotic weaponry in more detail. See here for more analysis by King.

Also, Charles Pegelow, a Structural Engineer, has come forward. He was interviewed on James Fetzer's radio show on November 30th, 2006 and MP3s of this show are here: hour 1, hour 2.
