You, Sir, are a cad.
I challenge you to a duel.
Beauty is in the eye of the beerholder. I just don't think jet fighters are pretty beasts. Of course fighters are always at the forefront of technology, and so are somewhat novel n appearance of necessity. The long snout, fat flanks and angular arse of a Phantom just don't do it for me. I will say the Lightning looks like it means business, two enormous engines, a pair of stub wings and that's yer lot.
Now the Spitfires (early marks before they docked about with the wings, canopy etc) are beautiful. But piston machines aren't in scope on this thread.
It must have been a hell of a learning curve going from a piston fighter to a jet fighter, especially one that was 2 or 3 times as fast as say a Spit.
