Three specific configurations, with three specific missions, are now on the horizon. Custer foresees a single-engine version (his first pilotless model was single-engine) for private use or small-scale business use, able to land on farms or remote forest areas where no airports exist.

He also foresees the most exotic configuration of all, a channel jet without any wings or tail section. The engine would be buried in the fuselage, with the scoop in the nose and exhaust in the tail. Channels would then be put in both the nose and the tail, doubling, he says, the lift capacity, because the craft would be, without any external appurtenances, a flying bullet, getting directional control by swiveling the tail channel, the way missiles control direction by swiveling the tail nozzles. The Devore firm, however, sees a "fantastic future" for a four-engine, two-channel passenger plane that could be the long-sought replacement for the venerable DC-3. Carrying 20 passengers, it could drop into and fly out of airports with no more than 300 to 500 feet of runway, making scheduled stops at just about any small town in the world. The engines, they said, are already built--turbines paired to drive one propeller through a gear box. The gears would allow the props to be turned either way, clockwise or counter-clockwise.
