Title: Orbiter "Enterprise" turns and banks during second ALT

Description:

The Orbiter 101 "Enterprise" makes a turn and bank maneuver during the
second  free flight of the Shuttle Apporach and Landing Tests (ALTs)
conducted on  September 13, 1977 at Dryden Flight Research Center in
Southern California.  The "Enterprise" separated form the NASA 747 carrier
aircraft and after a  five-minute, 28-second unpowered flight landed on a
runway below. Astronauts  Joe H. Engle, and Richard H. Truly were the crew
of the "Enterprise." The ALT  free flights are designed to verify Orbiter
subsonic airworthiness,  integrated systems operations and pilot-guided
approach and landing  capability and satisfying prerequisites to automatic
flight control and  navigation mode.
