The RPA route is a reason why the USAF needs to bring back Warrant Officers. However the USAF has a big anti-Warrant Officer sentiment, much like allowing Enlisted to fly RPA's. Somehow we can refuel aircraft in the air, load Abrams tanks on a C-5, calculate TOLD and be a systems expert on a CV-22, and fly as airborne linguists speaking Russian, Arabic, or Chinese...but we can't pilot RPA's.
