After a while pilots will simply forget the cameras are there. Who modifies what they say in the cockpit because of the CVR! Pilots will talk about all sorts of non-operational stuff while they are starting the engines then taxi for take-off. The NTSB has been wanting CVidR for a while so it is high on the list of priorities and it will provide answers to accidents that the CVR simply can't capture. If those who are so concerend about privacy are really serious then I take it they have no bank accounts, never use a credit card and have no internet connection. Unless you are living in the remotest hills of your particular country of abode then privacy is a concept that is as illusory as parliamentary democracy.
