North American X-15. If the type of engine is not limited to jet-powered engines, then the North American X-15 is the fastest airplane. Powered by a rocket engine, the X-15 is said to have reached a speed of 4,520 miles (7,274 km) per hour. Like the X-43, it is launched mid-air from a B-52.
Guinness World Records recognized NASA's X-43A scramjet with a new world speed record for a jet-powered aircraft - Mach 9.6, or nearly 7,000 mph. Answer The fastest speed wasâ¦ recorded by an unmanned aircraft called X-43. It can reach the speed of almost 7460 miles per hour. The fastest manned aircraft is X-15. Its top speed is 5115 miles per hour. This is very, very fast. Different ways of flight propulsion must have different categories as fastest in their method of power, to allow for this question to be answered properly. However, the overall fastest flight reached is Mach 9.8, which is about 12,144 km/h.
