Standby4321 hit the nail on the head. Positive identification of the crewmembers is the most important thing. Once that is accomplished, all this extra searching of crewmembers is a big waste of time that could be better directed elsewhere. Let's face it, once a pilot is at the controls you have to trust that he/she wants to get to the destination safely as badly as you do. Whether or not a pilot has fingernail clippers has NO BEARING as to the safe outcome of a flight.
