An unmanned Air Force space plane dropped out of orbit and glided to a computer-controlled California landing early Saturday to close out a classified 469-day military mission.
The reusable Boeing-built X-37B Orbital Test Vehicle touched down on a runway at Vandenberg Air Force Base, Calif., at 5:48 a.m. PDT (GMT-7). The Air Force did not provide any advance warning of the re-entry and landing time and no technical details about the vehicle’s performance were released.
