There was an earlier thread on this. IIRC, the destroyed tapes were "unofficial".

I see the earlier post now, but this one reveals the fact that the still-protected FAA bureaucrat went to great lengths to make sure the tape was never heard of (or from) again. Suggests -- unlike yesterday's post -- that he knew what was on the tapes after all and made d*mned sure it would never be heard.
