Reginald Leigh Dugmore, known professionally as Reginald Denny, was an English actor, aviator, and UAV pioneer.

Unmanned Aerial Vehicles (UAVs) include both autonomous drones and remotely piloted vehicles (RPVs). A UAV is capable of controlled, sustained level flight and is powered by a jet, reciprocating, or electric engine. In the twenty-first century, technology reached a point of sophistication that the UAV is now being given a greatly expanded role in many areas of aviation.
