Some folks in the 9/11 truth movement (example) have been very slow to realize that there is no evidence than any actual hijackings took place on 9/11, and abundant evidence that no such hijackings occurred. (I'm talking about hijackings by human beings not acting as part of a drill--there may well have been remote-control "hijackings" or bogus hijackings by people acting in a drill.) Likewise there is no evidence against any of the 19 patsies, and abundant evidence of their innocence.
David Ray Griffin's new article Phone Calls from the 9/11 Airliners: Response to Questions Evoked by My Fifth Estate Interview helps set the record straight on this issue, as does a free e-book by British journalist Rowland Morgan entitled Voices: The 9/11 Phone Call Evidence. Anyone who still thinks suicide hijackers flew the planes into their targets--and anyone interested in getting at the full truth of 9/11--needs to read these.
