Product Description
■ X-15 : After the defeat and occupation of Germany, the United States acquired a large number of aviation and space engineers, and received the report of the Zenger Program, which was a secret report of Germany at that time. This was based on the idea that rockets would fly over the upper atmosphere as if they were skipping, and that they would reach the other side of the Earth and bomb it. The existence of intercontinental ballistic missiles was a great threat at a time when the development of intercontinental ballistic missiles had not progressed much. Up to now, the official record of maximum speed and maximum altitude is still maintained.
