What is the fastest plane?

The fastest plane is X- 15, with a top speed of 7274 kilometers per hour.

The plane retired from the historical stage after serving for more than ten years. But its contribution to mankind is still great, because its flying speed has quickly caught up with the speed of launching rockets.

Therefore, some people say that this short-lived aircraft has played a key role in the development of human space industry, and also provided a lot of valuable technical information for human beings to better study rockets.

Extended data:

In the late 1960s, the United States flew the fastest hypersonic aircraft in the world, which was mainly developed by the US Air Force, the US Navy and an American aircraft manufacturing company.

The X- 15 aircraft has a long and smooth fuselage. There is nothing wrong with the whole aircraft except some necessary parts for flight. It looks not much different from the rockets launched in the United States now.

The speed of X- 15 aircraft can reach 7274 kilometers per hour, mainly because it is equipped with a rocket engine, and it is also the fastest manned aircraft developed by human beings.

The main parameters of the X- 15 aircraft are: the total length of the aircraft15.24m, the altitude of the aircraft 4.17m, the maximum takeoff weight10.53kg, and the maximum ascent height of about1000m.
