Relevant insofar as the FAA's credibility has taken a dent, it is perhaps worth re-posting a link to one of the interviews with DP Davies, the former ARB/CAA certification test pilot.
The fourth and final podcast covers Concorde and the British V-bombers. But listen on to about the 35 minute mark for his frank views on the FAA - even in 1992 he was shall we say decidedly skeptical...
I can't post a URL I'm afraid, but a quick search (the interviews are on aerosociety - dot - com) will find them.
