Because of cabin pressurization, airplane windows must be small - and
round - to avoid undue stress on the fuselage structure.  The higher the
cabin pressure differential (higher altitude) the more stress.  That's why
Concorde has VERY tiny windows, and why propeller planes that fly lower
sometimes have bigger ones.  (An abberation to this rule - the DC-8 had
very large windows for a jetliner.  The Caravelle and Sabreliner had
triangular ones.)
