The interesting bit of trivia here is that Boeing had to pay a thousand
dollars per airplane for the first couple of thousand 727's.  The patent
for hanging the engines on the aft side of the fuselage was held by a
French designer.  I think it was around 1700 airplanes before the patent
ran out but I don't quite remember.
