It may not have been the best fighter, but when it comes to looks... nothing comes close.
US planes are clumsy pigs
UK planes are like ducks with oversized wings
JP planes are like midget flies
USSR planes are smurfy radials on wood frames
Italian planes, with a long tradition of beautiful aircraft, are the only competition, but IMO a bit too sporty looking... pointy like a pencil, if you ask me.
Only the 109, holds the perfect balance. Slick, inline design with nice curves lines all around, light and nimble profile and yet doesn't feel like a dwarf, and the sinister feeling frontal profile that forms an accute "V" shape...
Ahhhhhhhhhhhh....
