I didn't see anything in there about the origination of the term "tailspin." If
you inferred from the article that the author made it up to aquire a name for
his character, this is certainly not true. The term "tailspin" was used during
WWI to describe some sort of spin, and French (at least) pilots were required to
demonstrate recovery from one before being assigned to combat. Nodhoff & Hall
state that "the tailspin had a bad reputation in those days" when writing about
their flight training in "Falcons of France." Both flew for France during the
Great War, and Norhoff was one of the top French aces.

no clothes on - and are up to somethin'.
