How to tell the difference between a drone, a plane and a UFO

Drones are being spotted all over the U.S in recent weeks.

On Tuesday more suspected sightings in the eastern U.S. led to a temporary airspace shutdown at an Air Force base in Ohio and arrests near Boston‘s Logan International Airport, as elected officials increased their push for action to identify and stop the mysterious unmanned flights.

Drones flying around Wright-Patterson Air Force Base near Dayton, Ohio, forced base officials to close the airspace for about four hours late Friday into early Saturday, said Robert Purtiman, a base spokesperson.

It is the first time drones have been spotted at the base, one of the largest in the world, and no sightings have been reported since early Saturday, Purtiman said Monday. He would not say how many drones were flying in the area, adding that they ranged in size and that they did not impact any base facilities.
