Crew Compartment Trainer
As STS-67 Astro-2 payload specialist Samuel T. Durrance looks on, astronauts Stephen S. Oswald, mission commander, and Wendy B. Lawrence, flight engineer, discuss troubleshooting communications problems during a training session at Johnson Space Center in October 1994. The three, scheduled to spend 16 days aboard the Space Shuttle Endeavour early next year, are in the Crew Compartment Trainer (CCT) at Johnson's Shuttle Mockup and Integration Laboratory. (NASA photo)
