Microwaves on the Way
With every revolution, some of them hit the lost plane and bounced back, making the blip on the radar screen which showed the plane's exact position. As the plane came closer, a second operator, watching the blip on a more finely scaled screen which showed details of the airfield, took up the coaching. Slowly the plane moved downward, until the roar of motors was heard outside. The plane had landed safely. Then someone pounded on the door of the truck. It was the fighter pilot. "Show me this new radar!" he demanded. "I couldn't see the ground at all, just felt a bump." This Ground Controlled Approach radar, which later at Iwo Jha "talked down" many crippled B-29s to safe landings, is only one of an Extremely Short Radio Waves Made Possible the War-Time Miracle of Radar. In Peace, Time, These Same Waves Will Bring New Impetus to Television as Well as to Radio Telephony, Telegraphy, and Facsimile. Microwave Beams Can Change Our Whole Communications Pattern
