Aerials of Orion on Launch Pad 37 from Helicopter

This helicopter view of Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida shows the United Launch Alliance Delta IV Heavy rocket as it stands ready to boost NASA's Orion spacecraft on a 4.5-hour mission. The liftoff was postponed because of an issue related to fill and drain valves on the Delta IV Heavy rocket that teams could not troubleshoot by the time the launch window expired.
