Space Flight (CTP1)

Space Flight is an advance in Civilization: Call to Power.
==Summary==
Space Flight, the fourth Flight Advance, opens space to mankind - to visit, but not to stay. Without better launch vehicles, the cost of constructing a complete Space Colony remains prohibitive. However, the improved rocketry and low-orbit satellites can serve to protect. Through SDI, Civilizations can reduce the threat of Nukes.

During WWII, experiments with rockets and jet engines advanced at a furious clip, especially in Germany. After the war, German scientists captured by the Americans and Russians became central in their development of Space Flight. In 1957, to the shock of all Americans, the Russians launched Sputnik. The cultural shock launched the Americans on a mad dash to the moon, but once there, the Americans found little or no commercial benefits to space.
