I come with the proposal for you Frizzank, one that a talented modder such as yourself could find quick and easy to do, but still make an awesome job of it. Black Arrow. The mostly unknown and unloved British launcher, cancelled after its first successful mission (putting Prosperous X-3 into orbit) in the promise of the US giving Britain a deal of using American rockets at a discounted price (therefore cheaper than Black Arrow). Once the UK dropped Black Arrow, the Americans convientely "forgot" about this deal. There is a Black Arrow pack, but not done very well and hasn't been updated since 0.19. Could you please consider turning your hand towards this forgotten launcher, and give it the chance at glory it deserves.
