S94-40081 (23 June 1994) --- Wearing a training version of a partial pressure suit, Jean-Francois Clervoy, STS-66 international mission specialist, secures himself on a collapsible seat on the middeck of a Shuttle trainer during a rehearsal of procedures to be followed during launch and entry phases of his scheduled November flight. This rehearsal, held in the Crew Compartment Trainer (CCT) of the Johnson Space Center's (JSC) Shuttle Mockup and Integration Laboratory, was followed by a training session on emergency egress procedures. Clervoy, a European astronaut, will join five NASA astronauts for a week and a half aboard the Space Shuttle Atlantis in Earth-orbit in support of the Atmospheric Laboratory for Applications and Science (ATLAS-3).
