were at the home of STUART ADGOCK observing his radar equipment during this search. No object was reported by ADGOCK during this evening and therefore Captain CROSS had no opportunity to observe his equipment in action, particularly in reference to the reported object at such phenomenal altitudes. No unusual objects were detected by the radar equipment of the U. S. Naval Reserve Armory during the entire evening.

Upon abandoning the watch on this evening, a meeting was held with Captain CROSS after leaving ADCOCK's residence in order to ascertain CROSS' opinion. CROSS stated he had found ADCOCK to be technically incorrect in several matters relating to radar theory and practice and, in addition thereto, had very grave doubts as to the capabilities of the surplus APN-7 radar set which had been adapted by ADCOCK. He stated, however, that he had insufficient opportunity to observe the set in practice or to examine the radio equipment connected with the set to make any definite statements as to whether or not the detection of the unknown object would be possible with said equipment. He said, however, he did feel that ADCOCK was a capable person with pure radio techniques.

On the morning of March 4, 1950 at 10:30 A. M. ADCOCK again contacted Special Agent McSWAIN of this office and Special Agent SEAGRAVES, OIC, to advise that he had again received indications of the object at approximately 100,000 feet directly over Oak Ridge and that the intensity of the radar "pip" was stronger than noted at any time previous. At about 11:40 A. M. ADCOCK again called and advised he had watched the object until approximately 11:10 A. M., at which time he had noted it stopped circling and headed off in an easterly direction at approximately 200 miles per hour, at which time it had faded from the screen in slightly less than 20 minutes.

On the afternoon of March 4, 1950, Colonel C. D. GASSER and Captain ROBERT GROSS, both NEPA, visited the home of ADCOCK and carefully examined his radio and radar equipment, including the antenna and related mechanisms. After such examination and after talking at some length with ADCOCK, these two gentlemen met with Special Agent SEAGRAVES (CIC), PRICE (OSI) and McSWAIN (FBI), to give their opinions. Colonel GASSER advised they had found ADCOCK in a much inscribed condition and that they had had difficulty in making any determination as to his abilities in the field of radar. It was their belief that his equipment was haphazard at best and that no great degree of reliability could be placed therein. They did state, however, they intended to return during the morning of March 5, 1950, which was the usual time for the object to be detected.

On the morning of March 5, 1950, Colonel GASSER and Captain CROSS went to the home of Mr. ADCOCK and were unable to gain entry or to find anyone at the residence. After this experience, it was the belief of these two gentlemen
