Hasn't Pontius rather knocked the idea of "specialist" crews on the head? If it is still the case that you have a limited number of aircraft ready to go/going and a new matter of interest arises, and the aircraft is detailed to investigate, then the composition of the crew comes to the fore. Does it matter if there are crew members underused because the mission has changed? And does this bring into question the relative multimission capability of the contenders among the available aircraft on the market.
