On my wish list are the B-58 Hustler (with interior and detailed escape capsule), and the B-36 variant that was used to test ability to shield crew personnel from an operating nuclear reactor (part of the nuclear aircraft testing program from late 50s-early 60s). Also of interest would be the proposed nuclear-powered cruise missile (Project Pluto).

And I still am plugging for a Martin B-10 (I know, FG has one....I want a REAL model of the beast).
