[sci.space.shuttle] Shuttle flap position during orbit

harman@vu-vlsi.Villanova.EDU (Glen Harman) (07/29/88)

In every picture of an orbiting shuttle I've seen, the "flaps" are in very 
similiar positions.  The port flap is raised, while the starboad flap is in     a neutral position.  I am curious;  What functions, if any, do the control      surfaces have during ascent and orbit?
