I absolutely love that car.  Being a nostalgia freak, if I ever built a 
streamliner, it would have to look like that.  I'd sacrefice absolute top speed 
just to enjoy the beauty of the car.  Every time I look at that car, I remember 
a film of a test airplane being dropped from the belly of a B-29 in the 
mid-fifties.  It was a pollywog shaped plane with either no wings or very tiny 
wings.

Looking at the Moon Equipment 2003 calendar with the Larsen-Cummins #115
streamliner on it raises another question. Lynn Yeakle designed the body on
that car in the 1960's when he was working for Lockheed at the "Skunk
Works." The car is fairly wide by today's thinking and has the flat Kam
back that was so popular on race cars of that era. I'll have to ask Jeff
Decker if he knows the curvature on that car. Fred gave him a copy of the
original drawings to use in designing the trophy bronze for USFRA. That car
has been so consistent and stable, even with a very short wheelbase that it
deserves to be studied. Probably a wind tunnel model, using that as a
starting point, could tell some interesting things about turbulence. That
flat back is wider than the chute tubes and shorter than the original
drawings. Hard to argue with success however.

Then there's the previously discussed vortex generators that could answer
questions on air management at the rear of a liner. It would be interesting
to see what difference they would make on a design like the #115 car.
