With the black box and flight recorders on planes, why not involve this. It would help with accusations and other issues dealt with on planes as well. The information could be fed from the camera to the black box so if god forbid something did happen, they would have the video stored to review.I don't see why this has not yet become mainstay on planes. Especially given all the new areas of concern. Even having the camera linked in the passenger area to the cockpit, since the door is locked, they can actually see what is happening if there is an issue. I think it would help immensely.
