jdray's Journal: Tuna-inspired aircraft runs on fuel cell

The startup R&D organization "Team SmartFish" has come up with a design for a performance aircraft that's inspired by a tuna fish, which is evidently (one of?) the fastest fish in the sea and has been clocked at 85 km/h. Their model-sized prototype is powered by a fuel cell stack with a pusher prop. The full scale version calls for a 900-1000# turbofan in the tail.

If this thing works out, I wonder if a small modification to put one of Rutan's rocket motors below the turbofan output would make this a viable sub-orbital launch vehicle.
