The SR-71 was created in the sixties...not exactly high tech! I don't think simulating a mach 3 aircraft on a server would be the best idea either....it'd probably crash trying to generate all those chunks!
I've been working on a futuristic pack, been a bit lazy about it, but it has been on my list of projects. Also, Vlad, I think he was just talking about making a more high tech vehicle with the general bodystyle of a SR-71. You have to admit, the body of the thing would work in some sort of futuristic pack.
I'll be thanked for killing a monster while you're burning in hell.
