Australopithecus, to quote you
"Well, I particularly liked the idea of cramming two observers onto the flight deck who would of course be unable to observe anything useful. Sharpening up a risk assessment gets an honourable mention too. Putzes."
Mate how about while the two pilots are heads outside aiming up the bombing run, the observers are watching over the inside and maybe, just maybe saying "guys you're 10 knots above the stall at idle thrust."
I'd consider that "useful observation" myself. Putz.
