"The X-37B Orbital Test Vehicle mission 4 (OTV-4), the Air Force's unmanned, reusable space plane, landed at NASA's Kennedy Space Center Shuttle Landing Facility May 7, 2017. "Today marks an incredibly exciting day for the 45th Space Wing as we continue to break barriers," said Brig. Gen. Wayne Monteith, the 45th SW commander. "Our team has been preparing for this event for several years, and I am extremely proud to see our hard work and dedication culminate in today's safe and successful landing of the X-37B." The OTV-4 conducted on-orbit experiments for 718 days during its mission, extending the total number of days spent on-orbit for the OTV program to 2,085 days."
