US secret spaceplane will come back to Earth sometime soon

The US Air Force is preparing for the imminent landing of its second secret spaceplane, which is expected sometime at the beginning of June.

The reusable X-37B, an unmanned shuttle with an unknown mission, will probably come down at Vandenberg Air Force Base in California, although Edwards Air Force Base in the same state is a backup landing site.
