Comment: I thought this was debunked?

William Rodriguez heard/felt something blow up below him - in the basement... he was about to tell his supervisor that it must be a generator - but before he could, they heard the huge crash of the plane striking the building. To Rodriguez and others, this is an indication that what actually blew up in the basement was the start of the government's explosive charges. ??

Of course, what probably really happened was exactly what William Rodriguez's first thought was - a generator blew up below him. This was caused by the plane striking the building. See - light goes much faster than sound. So, the generator blew up at the very moment the building was struck - the sound of the plane hitting arrived about 1 second later.
