(04/04/1997) --- STS-83 Pilot Susan L. Still gives a thumbs-up as she is assisted into her launch/entry suit in the Operations and checkout (O&C) Building. She is the second woman to fly in this capacity on a Space Shuttle. Still is a lieutenant colonel in the Navy and has more than 2,000 flight hours in 30 different types of aircraft. She also holds a master's degree in aerospace engineering. Still will assist Halsell with all phases of the space flight and will have primary responsibility to take action in the event of an emergency. After Columbia reaches orbit, Still will be busy with the many and varied tasks associated with monitoring and maintaining the orbiter. She and six fellow crew members will shortly depart the O&C and head for Launch Pad 39A, where the Space Shuttle Columbia will lift off during a launch window that opens at 2:00 p.m. EST, April 4
