    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.

    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.

    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.

    What's the fuel burn rate on that thing?

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