Hello Triton, I was wondering if this concept had blueprints, and specifications for range, capacity, etc. I would be highly intrigued if this does have any more info.

Is that smudge at the back just a mark on the print, or a contra-prop to supplement the in-wing jets ??

Yep, sure looks like a belt and suspenders approach...

Cannot help the feeling, that for this concept, someone put together the tail of the Douglas Skybus, the wing and maybe landing gear of the Martin XB-48, and the fuselage of the Convair XC-99. And especially for the latter, with
its double row of windows, the cockpit looks way to big to me ...

"... the cockpit looks way too big to me ..."

Given the era and engine count, would it have had two flight engineers plus navigator and comms ??
