The U.S. Department of Defense (DOD) wishes to dedicate a large block of airspace over North Dakota, eastern Montana, and northwestern Minnesota to theexclusiveuse of various military unmanned aircraft systems, some of which may be large, experimental, and/or fully autonomous.

• Can the DOD simply declare that airspace off-limits to civil aircraft?
• If not, how must the DOD proceed if it wishes to accomplish that objective?
• Will interested persons and organizations like Airlines for America and the Aircraft Owners & Pilots Association have an opportunity to express their opinions about the proposed change? If so, how?
