On March 2, 1950, he advised that his radar equipment recorded an object about 100,000 feet high and approximately 15 miles from his home in Knoxville at 11:15 a. m. on that date. It was reported that Naval Reserve radar equipment at Knoxville, Tennessee, did not detect an object on any occasion but stated that the equipment was not considered efficient for aircraft at extreme altitudes. It was further reported that qualified persons at Oak Ridge, questioned [REDACTED] and examined his radar equipment. They reportedly found his equipment not too reliable and felt that [REDACTED] was technically wrong on some of his radar theory. The reliability of [REDACTED] was also questioned due to some degree of inebriation. No investigation is being conducted by this Bureau but in the event additional information comes to our attention you will be promptly advised.
