Learn how technological innovations developed by MIT’s Radiation Laboratory, or “Rad Lab,” helped tip the balance of World War II to the Allied forces, in this video adapted from The Secret of Tuxedo Park: AMERICAN EXPERIENCE. Following the Japanese attack on Pearl Harbor, hundreds of scientists and engineers rushed to develop an automated radar device to detect and track an enemy aircraft in flight. Microwave radar systems greatly improved the shooting accuracy of defensive weapons and were used to neutralize the German army’s fearsome V-1 rocket bombs.
