Some of the press clippings in the file mentioned the Pentagon major and his concrete proof of Venus. I couldn't find this concrete proof in the file so I asked around about the major. The major, I found, was an officer in the Pentagon who had at one time written a short intelligence summary about UFO's. He had never been stationed at ATIC, nor was he especially well versed on the UFO problem. When the word of the press conference regarding the Mantell Incident came down, a UFO expert was needed. The major, because of his short intelligence summary on UFO's, became the "expert." He had evidently conjured up "they" and "their later report" to support his Venus answer because the writers at the press conference had him in a corner. I looked farther. Fortunately the man who had done the most extensive work on the incident, Dr. J. Allen Hynek, head of the Ohio State University Astronomy Department, could be contacted. I called Dr. Hynek and arranged to meet him the next day. Dr. Hynek was one of the most impressive scientists I met while working on the UFO project, and I met a good many. He didn't do two things that some of them did: give you the answer before he knew the question; or immediately begin to expound on his accomplishments in the field of science. I arrived at Ohio State just before lunch, and Dr. Hynek invited me to eat with him at the faculty club. He wanted to refer to some notes he had on the Mantell Incident and they were in his office, so we discussed UFO's in general during lunch. Back in his office he started to review the Mantell Incident. He had been responsible for the weasel-worded report that the Air Force released in late 1949, and he apologized for it. Had he known that it was going to cause so much confusion, he said, he would have been more specific. He thought the incident was a dead issue. The reason that Venus had been such a strong suspect was that it was in almost the same spot in the sky as the UFO. Dr. Hynek referred to his notes and told me that at 3:00P.M., Venus had been south southwest of Godman and 33 degrees above the southern horizon. At 3:00P.M. the people in the tower estimated the UFO to be southwest of Godman and at an elevation of about 45 degrees. Allowing for human error in estimating directions and angles, this was close. I agreed. There was one big flaw in the theory, however. Venus wasn't bright enough to be seen. He had computed the brilliance of the planet, and on the day in question it was only six times as bright as the surrounding sky. Then he explained what this meant. Six times may sound like a lot, but it isn't. When you start looking for a pinpoint of light only six times as bright as the surrounding sky, it's almost impossible to find it, even on a clear day. Dr. Hynek said that he didn't think that the UFO was Venus. I later found out that although it was a relatively clear day there was considerable haze.
