Flight is the dream of humans to move in an inaccessible, unknown world. To achieve this purpose, humans have always tried to invent devices and vehicles, which enable them to move in the sky. Due to the high velocity of the fly, the airplane has been widely developed for transportation for a long-distance journey. The advantages of flight in the sky have motivated the government to use this to fight against their enemies. Hence, various fighters have been invented that move at a higher speed than civil applications. Then, scientists have believed that they could access space with high-speed spacecraft, which moves in the outer atmosphere. In the atmospheric domain, the highest speed craft is available since existing gas in outer space is low density and cold.
