how about the pentagon planes black box...? was it found?
I believe the reason is, the hijackers gave big anti-American martyrdom type speeches before hitting, and we dont want to give them the air time or recognition as heros to their psycho followers.
No. The reason the government is hiding the FDR's is because in the last moments before impact, the terrorists confessed,
"Condoleeza phoned us directly and told us when the best date for this event would be. Bush and his father both approved and were meeting secretly with Osama's family to arrange for the transport of the bin Laden family members from these shores." - < ;-) (with a tinman tinfoil hat)
