Who is also bound, beyond a certain point, by security oaths. I will point out, though, that the "hump" contours of the F-35B could give you a good start toward the aft cockpit, even if you have a fuel cell in place of the lift fan. Also, consider the "swoop" of the cockpits of the F-5F as a guide to a suitable configuration that would maintain the chine line. The two-seater doesn't necessarily need to have the back seat higher (I don't think the Hawk back seat is much higher than the front and the MB.326 is the same way).
