The Washington area kept its eyes to the sky on Tuesday morning April 17, for a special over-flight by the Space Shuttle Discovery docked to its 747 carrier aircraft. The Discovery is moving to its new home at the Smithsonian’s Steven F. Udvar-Hazy Center in Chantilly. The Discovery has flown 39 missions, spent 365 days in space, and was the longest-serving orbiter in NASA’s shuttle program.
