Aerials of Orion on Launch Pad 37 from Helicopter

This helicopter view of the NASA Causeway connecting NASA's Kennedy Space Center with Cape Canaveral Air Force Staton shows the thousands of vehicles parked where guests gather to see the launch of the Orion Flight Test. 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.
