NASA's modified Boeing 747 Shuttle Carrier Aircraft briefly flew in formation over the Edwards Air Force Base Test Range on Aug. 2, 2011. The aircraft were scheduled to be in the air on the same day, NASA 911 (plane in the foreground) on a flight crew proficiency flight, and NASA 905 (rear) on a functional check flight following maintenance operations. Since both aircraft were scheduled to be in the air at the same time, SCA pilot Jeff Moultrie of Johnson Space Center's Aircraft Operations Directorate took the opportunity to have both SCA's fly in formation for about 20 minutes while NASA photographer Carla Thomas captured still and video imagery from a NASA Dryden F/A-18. In addition to Moultrie, NASA 905's check flight crew included pilot Arthur "Ace" Beall and flight engineer Henry Taylor while NASA 911 was flown by Larry LaRose, Steve Malarchick and Bob Zimmerman from NASA Johnson and Frank Batteas and Bill Brockett from NASA Dryden.
