Be forewarned. Military and aerospace companies are putting large $$$ to fund research and development of autonomous UAV/UCAV's. UAV are Unmanned Air Vehicle and UCAV is Unmanned Combat Air Vehicle. Keep in mind the military with its UAV/UCAV is in its infancy but all technologies developed from the military and space transition to the commercial sector. IMO, once the military has ironed out the software issues and start seeing operational squadrons of UAV/UCAV, you can bet your dollar that someone on the commercial side will try to transition that technology for commercial transportation.
