Ohio's Sinclair Community College has come up with a clever workaround for this problem. It's building a 40-foot tall drone arena that will let students in its aviation programs fly drones away from airports (where the programs currently have to operate) without worrying about licenses or nasty weather. Pupils will have to wait until the facility is ready in early 2016 to commandeer UAVs indoors, but it could give them a leg up in an aviation industry where pilots are increasingly optional.
