Re: Occams razor
The camera does not have to be tied into the aircraft's black box or any other system. It could be a normal self-contained dash-cam (or more usefully several of them covering different sectors). These are not for post-crash investigation, but to verify what the pilot(s) thought they saw. You'll probably find that many of the dones turn out to be birds, plastic bags or just momentary reflections or tricks of the light. As another poster stated, it is human nature to back up what another person you were with says they saw.
