Eagl,
They only let me play with the yoke, rudders and throttle type stuff.
Started in <cough> '75 as a co-pilot, left in '80 as an instructor.
But I did have more than a little idea of what was done in the back of the bus.
An amazing airplane for it's time. I got to fly a few sorties on the prototypes of what became the RC-135W just before I left. I never actually flew an "official" W; they were standardized after I got out.
I think though that a crossbreed JSTARS/RC on a 767 airframe would be the ideal platform. I'm sure it's an idea that has occurred to someone other than myself.
Hey, it's only money... and someone else's at that!
<Jeez, I sound like Tom Daschle there, don't I!>
