Since the topic of shuttle landings have come up, I have a question:

	What is the margin of error for the shuttle when making a
deorbit burn?  e.g. If the deorbit burn is done 10 miles to late/early
(I would think there is a larger margin of error than this)
than it should be, would it still be able to land at its target?
  Conversely, when a shuttle does come out of orbit, how big
of an area (on the ground) can the target be in?
