Remember the X-15, the space plane that nearly was ? USA could have been in space long before Russia if they have cleared a suitable flight plan. It had vectoring motors in the nose and tail and was all set to go but the program was stopped.
Maybe some of those futuristic designs we've seen around will come to fruition.
Cool
