Getting back to the original topic, for me the Rainbow is great looking until you hit the tail.
I don't like the look of planes with too much tail dihedral and the fin shape looks like the last bit of a bar of soap.
'Last bit of a bar of soap' - Quite describing, actually :-)
The sleek Rainbow could deserve the triple tail of the likely sleek Lockheed Constellation!
Other transition planes suffer the same problem where the tail doesn't match the design of the rest of the plane, the B-29 a bit, the jet Comet a lot.
Auch! I never saw, and will never be able to look at the Comet with the same eyes again :-o
