William Rodriguez's Story Partially Confirmed
A video has just surfaced which partially corroborates William Rodriguez's testimony. In it (the second interview in the video below), a worker states that there was an explosion in the basement of one of the Twin Towers, and that he saw a guy with his "skin hanging off".
While the gentleman being interviewed does not give a timeframe for the events he witnessed -- and the most stunning part of Rodriguez's testimony is that the sub-basement explosion occurred before the plane hit -- this is a step forward.
If anyone knows who the gentleman is, please immediately interview him on video to get clarification of when he witnessed the events. Also, see this interview which also partially confirms Rodriguez's testimony and this scientific paper regarding seismic evidence.
UPDATE: The gentleman interviewed has been identified as Kenneth Johannemann, an employee of ABM janitorial services, a division of ABM Industries Incorporated. stayreal found a still picture from the interview on the cover of a 2002 publication from ABM. It is impossible to tell when this web page was first posted to the Internet, however.
