The MD-80/90/95/DC-9 family is the extreme example of how far
a basic airframe configuration can be stretched. It seems you've
noticed some of the deficiencies of such a configuration.
However, the configuration has the advantage of having a clean
wing... and this should have some real benefit in terms of
reducing pylon/nacelle related induced drag. If nothing else,
it is an easier wing to optimize.

What's the fuel economy like on a MD-80/90? Better or worse than
a equivalent 737? (or 727? given the length of the MD-90)
