  Title: STS-56 inflight maintenance (IFM) air duct routing on OV-103's middeck
  Description:
  STS-56 inflight maintenance (IFM) repair on Discovery's, Orbiter Vehicle
  (OV)  103's, middeck was required to offset overheating problems with one
  of the  onboard experiments -- Detailed Supplementary Objective (DSO) 322,
  Human  lymphocyte locomotion in microgravity. This "elephant's trunk" fix
  was rigged  from the airlock's air recirculation duct to DSO 322's forward
  locker  location by Commander Kenneth Cameron.  The "elephant's trunk" was
  fashioned  from trash bags and other plastic items to extend an airline to
  the troubled  area.  DSO 322 is collecting data on the locomotion and
  migration of human  lymphocytes through intercellular matrix and is testing
  the rotating wall  vessel and the specimen temperature controller.  In the
  background is the  port side wall with the side hatch, middeck
  accomodations rack (MAR), and  shuttle orbiter repackaged galley (SORG)
  visible.
