I'm a big fan of airplanes since I was a kid, and more specifically of the 1935-1960 combat airplanes. I know a lot about them, but from an aesthetics point of view, I have some clear favorites. And without further ado, here they are!
JU-87 (Stuka)
Many people says it's horrible, but for me it's close to perfection!
ME-110
Spitfire
Wings are dorky, but I love its side silhouette, and as a whole, it's amazing (not to mention how good it was)
Hurricane and Tempest
Both from Hawker, I like them both
B-17
Some people hates the huge vertical stabilizer and rudder, but I think it looks pretty cool and distinctive (not to mention a big part of this airplane success). Of course, the B-29 was uber-cool, but the B-17 is the real thing
Hawk/Mohawk
Although used by France and UK, it was developed by USA. Dork look, but really cool, I think this and the Stuka are the planes people automatically think about when answered about WW2 planes
F6F Hellcat
Perfection!
P-61 Black Widow
If you don't think this is cool, you need a head check! (the black version is even better)
Mitsubishi Zero
It comes as no surprise that the coolest WW2 plane is a Japanese one. Of course, the infamous ZERO! Just drool!
and if the Zero wasn't enough, take a look at the J2M Raiden...
or the Tony..
...or the Ki-21!
Ilyushin Il 2
An iconic Russian airplane
MIG-3
A/S/L?
Macchi Saetta
The king of dork, but cool in its own particular way
Post your fave!
