Most aircraft with thrust reversers are capable of backing away from a
gate. The aircraft with wing mounted engines, however, rarely do so
because they can pick-up trash that is blown forward by the reversed
engine -- the higher engines on B727's and DC9's are less likely to have
this problem, and as a result, a number of airlines have used this
procedure to save time and money.
