Speaking of round vs. square windows, I noticed that all versions of
the Boeing Stratocruiser had circular windows except those operated 
by Northwest and United.  Was there a technical reason for this?  (I
have the impression that these were later models than, say, the Pan Am
and BOAC ships.)  Or was the window shape changed because of customer
preference, to give the passengers a better view on those long overwater
trips?  :)
