Air Radar

In 1947, the first U.S. radar for commercial and private planes was first demonstrated at Culver City, California on a TWA airplane. In the cockpit, both a bright red panel light and a horn warned the pilot if the plane was not at a safe distance from obstacles to flight. The device was developed at the Hughes Aircraft Corp. by Howard Robard Hughes and a team of electronic engineers.
