Drones have had an explosion of applications in recent years. The driving force for drone development has been for military applications. But as with many new technologies, the uses have expanded to civilian and commercial applications. At first drones were an annoying toy used by individuals to fly around neighborhoods. These were not only a nuisance but caused a potential threat to commercial aviation. The on-line shopping company Amazon elevated the use of drones to a commercial level as a possible delivery system. The link below presents a number of uses for drones. Some of these uses are trivial and others are almost science fiction. One thing is certain, the use of drones will expand in ways that we can barely conceive. I'm not sure I want my pizza delivered by a drone in freezing, raining weather, but other uses are sure to be more appropriate.
