Astronaut William S. McArthur in training for contingency EVA in WETF

S93-43840 (6 Sept 1993) --- Astronaut William S. McArthur, mission specialist, participates in training for contingency Extravehicular Activity (EVA) for the STS-58 mission. For simulation purposes, McArthur was about to be submerged to a point of neutral buoyancy in the Johnson Space Center's (JSC) Weightless Environment Training Facility (WET-F). Though the Spacelab Life Sciences (SLS-2) mission does not include a planned EVA, all crews designate members to learn proper procedures to perform outside the spacecraft in the event of failure of remote means to accomplish those tasks.
