  Title: STS-31 Mission Specialist (MS) McCandless in EMU prior to JSC WETF simulation
  Description:
  STS-31 Mission Specialist (MS) Bruce McCandless II, fully suited in an 
  extravehicular mobility unit (EMU), stands on platform before it is lifted 
  and lowered into the 25-ft deep pool of JSC's Weightless Environment
  Training  Facility (WETF) Bldg 29. Once underwater, McCandless will achieve
  a neutrally  buoyant state and will rehearse extravehicular activity (EVA)
  procedures  associated with the Hubble Space Telescope (HST) payload. 
  There are no EVAs  planned for the flight aboard Discovery, Orbiter Vehicle
  (OV) 103.
