in 1956, the CIA dramatically breached the Iron Curtain when its U-2 began overflying Soviet territory to photograph that nation's military installations. Four years later, the Soviets would shoot down pilot Francis Gary Powers and his U-2, thereby ceasing these missions. Within months, however, the CIA had another, and better, technical program in operation – the CORONA satellite. Throughout the Cold War and beyond, the CIA's scientific wizards would continue to devise high-tech ways to collect and analyze information about potential adversaries. Their mission was of such importance that a new branch of the CIA was created – the Directorate of Science and Technology.
