That's not 100% true.
The CVR cannot be used to prosecute, but I can assure you from personal experience that it IS used. I have seen it played for pilots, and I have seen them handed transcripts in discipline hearings. I have also seen it vindicate pilots. And remember this, while the laws bar the company from prosecuting you THIS TIME, if the CVR shows you guilty, rest assured that they will be watching you closely and waiting for you to do something they CAN get you on. Seen that too.
Better check your facts. I can give you a list of names for your research.
Are you on crack? The company didn't save anyone, the union did! The company tried to fire both of them. ALPA saved their jobs, then the CA quit. The FO is still here. Ask him the story sometime. And I wouldn't automatically characterize a new captain on his first flight off IOE who makes a dumb mistake as a "wacko". You usually make well reasoned posts, but you are losing credibility here. Did the real Geekmaster forget to log out?
Your GUESS. 'Nuff said!
