An Israeli-built Elbit Systems Hermes 450 unmanned aircraft is towed out of a hangar at the Hillsboro, N.D. airport on Friday, May 20, 2016, before its first flight to collect agriculture data. It is believed to be the first drone of its type to be tested in the United States, as part of a joint project between North Dakota State University and the Northern Plains UAS Test Site.
