A scramjet (supersonic-combustion ramjet) is a ramjet engine in which the airflow through the whole engine remains supersonic. The highest speed attained by a rocket-powered airplane, NASA's X-15 aircraft, was Mach 6.7. The fastest air-breathing, manned vehicle, the SR-71, achieved slightly more than Mach 3. The X-43A more than doubled the top speed of the jet-powered SR-71.
A three-stage rocket can reach about three times the speed of a single-stage rocket. Most spacecraft are launched into space on top of a three-stage rocket. The first stage or booster, is the biggest because it has to lift itself, the other rockets, and the spacecraft through the densest part of the atmosphere.The booster fires for only one or two minutes before its fuel supply is exhausted. three-stage rocket can reach about three times the speed of a single-stage rocket.
