The Federal Aviation Administration announced six states on Monday that will develop test sites for drones, a critical next step for the march of the unmanned aircraft into U.S. skies.
Alaska, Nevada, New York, North Dakota, Texas and Virginia will host the research sites, the agency said.
Drones have been mainly used by the military, but governments, businesses, farmers and others are making plans to join the market. Many universities are starting or expanding drone programs.
"These test sites will give us valuable information about how best to ensure the safe introduction of this advanced technology into our nation's skies," Transportation Secretary Anthony Foxx said in a statement.
The FAA said when selecting the sites it considered geography, climate, location of ground infrastructure, research needs, airspace use, aviation experience and risk.
