Fed Ex and UPS will be the first customers
I think the rubric of 'single pilot' is a ruse, the program is obviously aimed at achieving autonomous flight. Moreover, as 'racedo' has pointed out earlier, the cargo lines are obvious initial users, they fly at odd hours and would love to rationalize their operations with fully automated cockpits. So there is a clear path to front line service, beginning with the military, then law enforcement, then cargo and eventually passengers. The technical and ATC obstacles are real, which is why Germany has just been forced into a humiliating cancellation of their planned multi billion Euro Hawk drone program. In this context, this 'single pilot' initiative seems simply an admission that the state of the art is not yet there and therefore taxpayers need to pony up to help close the gap. Obviously pilot unions are asleep at the switch, otherwise they might ask what is the purpose of this investment.
