The Pentagon's secretive X-37B spaceplane landed in Florida on Sunday after a record-long orbital flight lasting more than two years, the U.S. Air Force said, capping the latest test mission for an array of military technologies. The unpiloted X-37B, built by Boeing Co., touched down on an air strip at NASA's Kennedy Space Center at 3:51 a.m. ET after spending 780 days orbiting Earth as the Air Force's fifth flight mission under the Orbital Test Vehicle program, the Air Force said.
