  • There are problems other than just technology in going much faster than 65MPH/120KMH on the ground, and we are probably never going to see ground travel faster than that (except by rail, and that has so far not proved economically viable.) As mentioned previously, the problem with going faster than sound is really one of economics, not technology.
