Therefore the wings prevent any really bad effects from re-entry. Actually, protecting them from launch effects is the worse problem. ----------------------------------------------------------------------------- Dan Corbett University of Technology, Sydney

Actually, protecting >them from launch effects is the worse problem. > There are umbilical ports located between the wings and the OMS (orbital maneuvering system) pods. They provide conections with the ground servicing equipment. The 17 inch disconnects, however, are the umbilicals to the external tank. Both (one for the oxygen and one for the hydrogen flow) are located on the underside of the shuttle. As H Spencer indicated in a post, there are black tile covered doors which close over the umbilical panes during reentry. -------------------------------------------------------------------- Eustace | Bright red pepper pod... | It needs but shiny wings and look... spgreg@csd.lerc.nasa.gov | Darting dragonfly! | -Basho --------------------------------------------------------------------

From NSTS-3:
"An umbilical retraction system retracts the orbiter umbilicals within the
orbiter aft fuselage, and umbilical doors close over each of the umbilical
cavities after separation."
