The double-seat one look better because it solve the issue of long-back. However, given such a large canopy without frame, I think it's impossible unless they have super strong glass.

Yes its much more nicely proportioned and also has larger vertical stablizers, where the engineer will probably tell us, I told you it wasn't that long, right Eng. I do love this version, it looks right, and the larger stabs are more in proportion with the rest of the airplane. Nice job, who-ever drew this up, it might beat the raptor in a beauty contest now??? not sure yet?? brat

I always thought the canopy section looks too much like the MiG 17 from the side profile... LOL

Ahhh, the lovely Mig, the first with an afterburner, I saw one flying at Oshkosh twenty years ago, with the jet war birds, the burner isn't too impressive, it looks rather like a propane torch when it lites, nothing like the burners on the BONE, they sound like they are shredding the air to pieces, but it is a very lovely airplane, much like the Mig-15, beautifull an sweet, with a nasty side if crossed??brat

The funny thing is, J-20's back is not actually flat, like that of the F-111 or Mig-25, but actually cambered. The problem is that the camber starts pretty abruptly at the back of the cockpit. Also, unlike the raptor, the area above of intakes are actually flat. This makes the plane pretty unappealing when viewed from the side or from the front. It is best viewe from the top or from the bottom.

The designer will always look at the aerodynamics requirement first. Like the case of the surface being flat above the intake, too much camber at these surfaces could produce too much forward lift for an aircraft with the J-20 design configuration, making it very unstable. IMO, aesthetics can come naturally or is only considered when it does not compromise performance or go against design requirement.
