NASA Flight Director Confirms 9/11 Aircraft Speed As The "Elephant In The Room"

[Carsten Wiethoff]

Could some one refresh my memory about the black boxes? If I recall correctly the ones that were 'found' the recordings were never published, is that right? And the victims families were allowed to listen to some of it but not all and they were not allowed to talk about what they heard. What about the data from it? That would show flight speed etc?

In a nutshell: Only the Cockpit Voice Recorders and the Flight Data Recorders from AA77 and UA93 were supposedly found, so none of the WTC aircraft, which do have the speed issues.
The CVR from AA77 did not contain usable data (Huh?). The content of the FDR from AA77 is fully published (FOIA from several people did contain a "raw" data file). Thanks to the efforts of several researchers, there exist independent "readouts" for this, containing, for example, radar altimeter values, which were not contained in the NTSB readout.
The CVR from UA93 was allegedly played to the victim families and a transcript of the last minutes was later published. The FDR of UA93 was also fully published and an independent readout exists.
