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 question we often hear. The topic âWhich is the Fastest Aircraft in the Worldâ is not that simple. Some count the fastest vehicle, the Apollo module as record holder. The command module had Top Speeds around Mach 30, that is around 36,750 km/h or over 22,830 mph. But the Apollo canât be counted as Aircraft.
