     Several centuries ago when I was an undergraduate in the Aeronautical
Engineering department at MIT, the professor who taught the introductory
aaircraft stability and control course (name available on request) said
that the name Dutch Roll is used because the motion of the aircraft seems
similar to that of an ice skater slowly gliding down the frozen canals of
the Netherlands.
     I was not aware that the motion occurs only on swept wing aircraft.
