Looks great, but, since they have already done an outstanding B-52, how about a quality KC-135? I know the 707 and KC are different in most ways, should be easy to modify.
And while they're at it, how about a b-52 expansion with a D model, and a G without all the crap hanging on to it. (put some Hound Dogs on the wing and some Quails in the bomb bay).
Also, someone needs to do a native FSX B-58. I think Alphasim was doing it a while back.
