OGDEN – Hill Air Force Base officials said Monday there have been recent drone sightings close to the base, amid numerous mysterious drones being reported on the East Coast. The unmanned flying objects have been seen over New Jersey, New York and Pennsylvania, even shutting down Wright-Patterson Air Force Base’s airspace in Ohio, according to TV station WCPO. White House national security spokesman John Kirby said Monday there have not been any public safety or national security risks from the sightings, the Associated Press reports.
