WWII Fighters
P-38 - It's big, but it's sleek & powerful looking.
F4U - What's not to like about the bent wings and that HUGE prop?
FW-190 - Damn nicest looking radial engined airplane ever. It's got fabulous lines
WWII Bombers
A-26 - It's a clean looking airplane. It doesn't look bit and bulky like a normal buff.
FW-200 Condor - Looks like a cleaned up big brother of the C-47
PBY - Mostly not a bomber, but it did do some bombing. It's so ugly that it's beautiful!
Modern day
F-14
Panavia Tornado
