  Title: STS-31 Mission Specialist (MS) Sullivan during JSC WETF underwater simulation
  Description:
  SCUBA-equipped divers look on as STS-31 Mission Specialist (MS) Kathryn D. 
  Sullivan releases a pip pin on the Hubble Space Telescope (HST) Support 
  System Module (SSM) forward shell mockup during an underwater simulation in
  JSC's Weightless Environment Training Facility Bldg 29 pool.  Sullivan is 
  suited in an extravehicular mobility unit (EMU) as she practices 
  extravehicular activity (EVA) operations.  Though no EVA is planned for 
  STS-31, two crewmembers train for contingencies that would necessitate 
  leaving the shirt sleeve environment of Discovery's, Orbiter Vehicle (OV) 
  103's, crew cabin and performing chores with the HST payload or related 
  hardware in the payload bay (PLB).
