More 9-11

I just watched a documentary on Channel 4 entitled 9-11 The Lost Tapes. Programme title refers to lost tapes, but blurb says they are "newly released." American Aiirlines were pioneering airborne mobile phone calls in 2004, according to this article - http://www.usatoday.com/money/biztravel/2004-07-19-aircells_x.htm yet in the documenatry we hear a crystal clear recording of a fllight attendant apparently phoning air traffic control from a plane in 2001. And the hijackers allegedly turned off the transponder in the plane meaning that ATC lost it. Was the transponder turn off-able from within the aircraft and if so why and  how did the hikackers know how to do it?

The documentary reminded me of the interview with Elizabeth Woodworth of Consensus 9-11 that I saw some months back but didn't blog. Consensus 9-11 don't put forward conspiracy theories about 9-11, but they do have a lengthening list of consensus points about where the official account of what happened is untrue. They reach consensus using the Delphi method.
