A transfer tunnel permitted "indoor" passage of astronauts and equipment between the Space Shuttle's mid-deck crew cabin and the Spacelab laboratory module in the Shuttle's open payload bay. The pressurized tunnel had both a straight section and a joggle or elbow section to compensate for the different heights of the mid-deck and module entry hatches.
McDonnell Douglas manufactured the tunnel. NASA transferred the joggle section to the Museum when the Spacelab program ended but kept the straight section for use on other Shuttle missions.
Transferred from NASA Kennedy Space Center.
