The Flight Data Recorders would have wound up in the impact zones, for reasons that should be obvious.
Only a scant few pieces of structural steel -- solid pieces of steel, some inches thick -- from that area survived the fire and subsequent collapse with their markings intact.
FDR's are a mere 1/16" thick steel on the outside. And unlike the majority of structural steel, they definitely participated in the collision first. How likely do you think it would be for them to survive, when vastly tougher materials did not?
Even if we ignore this, what do we expect the FDR's could possibly show that would blow the whole case open?
Fixation on the WTC FDR's is a Conditional Irreducible Delusion. There's no mystery here, folks.
You're kidding aren't you?
The FAA has placed durability requirements on the recorders and their casings to survive severe impact and fire
The storage medium of each recorder is located in a protective capsule, which must be able to withstand an impact of 3,400 Gs (3,400 times the force of gravity). Additionally, each must also survive flames at 2,000 F for up to 30 minutes, and submersion in 20,000 feet of saltwater for 30 days. Typically, to increase their chances of survival, the recorders are located in the tail section of the aircraft, which usually sustains the least impact in a crash. 8
