All your failed ideas are cherry picked from the media; how ironic and such a dirt dumb statement. You and HI have exactly the same pile of evidence. the empty set; if you understand math you will figure out that means zero.You should know by now if you ask the people on here for answers the just repeat what the media has told them to believe.
The crack NSA agent who does not understand COMSEC rules and can't read his own post for facts or comprehend he just debunked, refuted, and made his position super stupid.http://www.airdisaster.com/investigations/af296/af296.shtml
It is not unprecedented where Flight Data Recorders have been switched/planted. The Institute of Police Forensic Evidence and Criminology have determined that the FDR recovered from the crash of Air France 296 is "either... not... the DFDR of the crashed Airbus A320 on the photograph... or the DFDR presented at the trial is NOT the one from the crashed Airbus A320." .
The article says the caught them switching the FDR! CAUGHT! The same would happen on 911 because it is too hard to fake it. The winds alone would catch the switch..
So it is a big lie to imply FDR are planted. They produce one instance where the idiots were caught; and this is if the story is true.
So you failed again; your NSA training was to post dirt dumb statements and debunk yourself.
Your post was plagiarized and you never presented the regulation that requires serial number to be used to identify planes in crashes you presented a pile of lies.
Got something else? Like identification of flight 77?
