The Grand Sky UAV Business Park outside Grand Forks, North Dakota (adjacent to the Grand Forks AFB) is a 217 acre complex that is positioned to be one of the larger UAV hubs in the United States. It is planned to have 1 million square feet of hangers, classrooms, warehouses, shops, and other support buildings.
The manager of the complex plans to push the FAA with flights to force a timeframe of approval of commercial flights, as of now it is slated for September 2015, but may not hold to that schedule. Growth could be large, current estimates have a $91 Billion industry by 2020. The article mentions that UAVs are “the new internet”, it may not go that far but as I have written on just some markets and applications it can be a profitable business model.
