S94-37526 (28 June 1994) --- In separate life rafts, astronauts Donald R. McMonagle (right), mission commander, and Curtis L. Brown, pilot, are assisted by several SCUBA-equipped divers during an emergency bailout training exercise in the Johnson Space Center's (JSC) Weightless Environment Training Facility (WET-F). Making their third and second flights in space, respectively, McMonagle and Brown will be joined by three other NASA astronauts and a European mission specialist for a week and a half in space aboard the Space Shuttle Atlantis. The flight will support the Atmospheric Laboratory for Applications and Science (ATLAS-3) mission.
