This Day in History:
August 8, 1951
McDonnell test pilot Bob Edholm completes the first flight of the XF3H-1 Demon, a prototype Navy carrier-based interceptor powered by a Westinghouse J-40 turbojet. The XF3H-1 is designed to carry air-to-air radar guided missiles as well as four 20mm cannon. The J-40 proves to be a failure, putting the F3H program in jeopardy until the plane is re-engined with the Allison J-71.
