The ironic part of the reluctance to accept cockpit video recorders is that the objections are being undermined by all the airline pilot u toobers and social media junkies who are recording their day at work. They are assuming that all those Go-Pros and selfies will not be made available to investigators if their approach to whatever holiday island goes pear shaped. I remember seeing a video from an engineer's phone who was sitting in the jump seat of an Air New Guinea 737 that landed short of the runway in a heavy shower. The video showed the Captains ND with the magenta line going to the runway but the wx radar overlay showing a big mass of red on the final stages of the approach. In the absence of any call outs by the PNF the CVR and FDR would not tell the investigators the full story of that approach. The video showed the investigators what the pilots saw. So there is already de-facto cockpit video recorder so the industry should just mandate it and put similar protocols around it similar to the CVR and FDR.
