The case involves an Air Force RB-47 on a flight over four southern states (Mississippi, Louisiana, Texas and Oklahoma) during the pre-dawn hours of July 17, 1957. An account of the incident was published in the July, 1971, issue of the AIAA magazine Astronautics & Aeronautics (p. 66). It was written by the late Dr. James E. McDonald, an outspoken proponent of the hypothesis that the Earth is being visited by space-ships from other worlds. McDonald’s investigation convinced him that an “unusual craft,” which had the ability to fly at supersonic speed and to hover, had “played tag” with the RB-47 for approximately two hours. The presence of the “unusual craft,” McDonald believed, was confirmed by three independent means: visual sightings by the RB-47 pilot and co-pilot; by electronic intelligence (Elint) equipment aboard the RB-47; and by an Air Defense Command ground radar located at Duncanville, Texas, near Dallas. In another published paper on the RB-47 incident, McDonald called it “a case in which the reported phenomena appear to defy explanation in terms of either natural or technological phenomena.” (UFO symposium sponsored by the American Association for the Advancement of Science in Boston, Dec. 27, 1959.)
