I think the NTSB should monitor the CVR as mentioned above.
BUT , the quid pro quo flo has to be : full restoration of pensions reasonably expected on sept. 10, 2001
and restoration of full pay, with back pay of expected wages as of sept 10, 2001.
In other words, UNSCREW all the pilots screwed over by 911 attacks and you can listen or watch us do everything.
