This test could pave the way for future manned launches and ABC's senior transportation correspondent David Kerley joins us from cape canaveral in Florida with more on this mission. David, good morning to you. Reporter: Good morning, Dan. The dragon capsule is orbiting the Earth at this hour. It still faces a couple of serious tests but so far so good. Ignition, liftoff. Reporter: This thunderous takeoff a major step forward in returning Americans to space from American soil.
