The first HTV-2 flight was launched on 22 April 2010. The HTV-2 glider was to fly across the Pacific to Kwajalein at Mach 20. The launch was successful, but the first mission was not completed as planned. Reports stated that contact had been lost with the vehicle nine minutes into the mission. In mid-November, DARPA revealed that the test flight had ended when the computer autopilot had "commanded flight termination". According to a DARPA spokesman, "When the onboard system detects or unsafe flight behavior, it forces itself into a controlled roll and pitchover to descend directly into the ocean." Reviews found that the craft had begun to roll violently.
