DC-10 #2 reverser
#2 DOES have a reverser, although it is inhibited until the nose gear squat switch is closed.
Related subject: One astute F/E wrote a paper that the DC-10 should cruise more efficiently with #2 at a reduced power setting, because trim drag would be reduced.
He would have been correct except for the fact that thrust falls off faster than fuel flow as the golever is retarded (i.e. SFC deteriorates).
