Supersonic Flights

With the last flight of the Anglo-French concorde more than a decade ago, civil supersonic flights have only been a dream but could that come to an end. "Yes!," I think so, and I am not the only one with such thoughts. NASA thinks it is on the right trajectory in respect of that. Maybe so but imagine flying not only under supersonic speeds (mach 2-5) but hypersonic speeds (mach 5 and above). Is it a distant reality? No, if the revolution in technological advancement catches up with the civil aviational industry, the impossible becomes possible!
