    I'm not sure of the utility of a 4-engined experimental.

      What's the fuel burn rate on that thing?

        Looks like the same problem as the Cessna 620 -- too many engines -- thus too much maintenance and too much fuel burn for the mission. At that time (before ETOPS certifications), a transoceanic plane would have needed three or more engines, but I doubt the thing had the range to do it.
        Life may not be the party we hoped for, but while we're here, we should dance.

          The promo talked about going to Europe. Also about going to Asia via Honolulu or Alaska.

          I think you just got hit on the design idea behind so many engines.

            It seems it was designed to compete with the Lockheed Jetstar for US military. The Jetstar (also 4 engine) won the competition.

            220 had a range of 2000 nm, at 452 knots. Specific fuel consumption was 1.04 pounds per hour per pound of thrust. But the movie did say production aircraft would have turbo fans. A set of William FJ44 engines could cut the specific fuel consumption to around 0.460.
