not only does the shuttle have to appear above the horizon to be visable,
but it must do so while the observer and most of the atmosphere above him
are in darkness, but the shuttle is still illuminated.  this is a rather
rare event for objects in low earth orbit, and is even more so when
you constrain it by the observer's location and weather conditions.
this should explain the paucity of suitable viewing locations and times
promulgated by nasa.
