This is the best cost and weight savings idea I have heard in a long while. I understand the benefit of having two brains in the cockpit. But does one of those brains have to be actually sitting in the cockpit? Versus sitting in a nice safe room someplace.
I made arguments like this when Comanche was still in development, and the Force XXI vision was being realized. (In a few of the meetings I was in). There are certain paragidms the US Army has great difficulty in shifting. This is one of them, and it doomed LHX/Single pilot concept.
