Chооse the mаin pаttern оf orgаnization of the passage. In the early 1900s, few people understood what could be done with rockets, and financial support for rocket development was difficult to obtain. It was not until 1926 that Robert Goddard launched the first liquid fuel rocket. Despite Goddard’s successes, rocket development in the United States proceeded very slowly with little government interest. It was Germany that brought about the rapid development of liquid fuel rockets in the late 1930s and early 1940s. The German V2 rocket, developed under the direction of Wernher von Braun (1912–1977), was the first missile to travel faster than the speed of sound, covering approximately 200 km in 5 minutes. The V2 was a potent terror weapon, and thousands were launched toward Antwerp and London during World War II. After the war, the Allies carted off every source of information about V2 technology that they could find, including von Braun himself, who eventually helped the United States put a man on the moon.
