[color=blue][b]From the doodlings of da Vinci and the penned fantasies of Jules Verne to the tangible accomplishments of the Wright brothers and other aviation pioneers, mechanized flight has captured the imagination of humanity through the centuries.
Even today, with atmospheric and space flight a reality, there are still aviatory realms to dream about and conquer. Hypersonic flight at speeds 5 to 12 times the speed of sound (Mach 5 to Mach
12) is one such area of interest to the commercial and defense communities.
At Lawrence Livermore National Laboratory, aerospace engineer Preston Carter has invented a concept for a next-generation hypersonic aircraft, dubbed HyperSoar, that could fly efficiently, economically, and cleanly.
Flying at Mach 10 (3 kilometers per second), HyperSoar could reach any point on the globe within two hours. (The fastest military plane, the SR-71, flies between Mach 3 and Mach 4, while the commercial Concorde only reaches did Mach 2.) HyperSoar would also have twice the fuel efficiency of commercial airliners, be three to five times more efficient in putting satellites in space than today's launch systems, and use liquid hydrogen fuel, which produces simple water vapor when burned.

in case of an accident you get liquidated and be part of the atmosphere in a mili-second

@Intelligentsia …the Delta II Rocket launchers carrying space crafts has to do the escape velocity which is equivalent to 11km/s or mach 34, in order to escape the earth's gravitational influence.
