“We are the first to have given a rocket a speed of 3,300 mph. We have thus proved that it is quite possible to build piloted missiles or aircraft to fly at supersonic speeds. We did it with automatic control. Our rocket today reached a height of nearly 60 miles. We have invaded space; we have proved rocket propulsion practical for space travel.” Walter Dornberger
During the late 1920’s and throughout the 1930’s progress progress in rocket design was made in fits and starts with unclear goals. However, many technological advances in liquid fueled rockets were made. The United States Germany, Russia, France, Italy, and Great Britain all had rocket research programs. The most significant advances occurred in Germany, the U.S. and Russia. But, before we proceed with the history, I want to explain how a liquid fueled rocket works.
