It occurred to me recently that while L1011's are starting to fall to the
scrap-man's torch fairly often these days, DC-10's (same generation,
approx. same size) are soldiering on as long-haul passenger aircraft
throughout the world, and in fact some are even being overhauled to start
new lives as freighters.

Is there a good reason for this? - plain old economics or did the DC-10
airframe have a lot more "life" designed into it?
