As far as manless flights are concerned drones are already there remotely flown.. As far as a commuter aircraft or the one from commercial airlines goes,,atleast for now flying an aircraft full of passengers being flown in absence of pilots onboard is sth I am not sure FAA regulations allow.. Even FAA part 23 and 25 aircrafts have different regulations as far as requirements for number of pilots  onboard is concerned..
I am sure it is a great idea,,probably cannot be termed as invention..
anyways good luck
