I guess beauty really is in the eye of the beholder. I never liked the looks of the Phantom but it’s predecessor, the F-101 Voodoo was a real beauty.
Now I always thought the WWII Spitfire was the prettiest plane ever tho the ME-109 and the P-40 were also beautiful.
Of current planes the F-15 looks the best to me.
F-101 is a cool plane but it’s no F-4, in my worthless opinion.
F-4 is sort of the Harrison Ford of fighter jets. It just looks the part somehow.
