Hanging on the wall at the Hiller Aerospace Museum are a number of paintings of conceptual airliners. Most were, or seemed to be, Boeing designs. Here’s one of a tandem-wing geometry.
It’s clearly related; the overall geometry is nearly indistinguishable. However, the -732 was a double decker, and clearly much larger. It would not surprise me if this was a Model 767-XYZ design of some kind, though.
Looks to me like some bored designers screwing around one day.
Stress from that rear wing’s drag is going to be murder on the structural weight of the aft fuselage.
Also – where, pray tell, is the landing gear supposed to go?
The basic design has been studied extensively. Getting the wing away from the fuselage has some drag benefits, IIRC, and hoisting it way up there puts it out of the way of tip vortices from the canard during high angle of attack flight. Landing gear would be in the fuselage, which would hardly be a new innovation.
it’s very similar to the model 767-732 from eAPR v1n6, page 86.
