In about twenty minutes I got my call. It probably was their balloon, the forecaster said. Above 50,000 feet there was a strong flow of air southeast from Pittsburgh, and this fed into a stronger southerly flow that was paralleling the Atlantic coast just east of the Appalachian Mountains. The balloon would have floated along in this flow of air like a log floating down a river. As close as he could estimate, he said, the balloon would arrive in the Gordonsville- Blackstone area in the late afternoon or early evening. This was just about the time the UFO had arrived. "Probably a balloon" was a good enough answer for me. The next morning at 8:00A.M., Al Chop called from the Pentagon to tell me that people were crawling all over his desk wanting to know about a sighting in Virginia. The reports continued to come in. At Walnut Lake, Michigan, a group of people with binoculars watched a "soft white light" go back and forth across the western sky for nearly an hour. A UFO "paced" an Air Force B-25 for thirty minutes in California. Both of these happened on June 18, and although we checked and rechecked them, they came out as unknowns. On June 19 radar at Goose AFB in Newfoundland picked up some odd targets. The targets came across the scope, suddenly enlarged, and then became smaller again. One unofficial comment was that the object was flat or disk-shaped, and that the radar target had gotten bigger because the disk had banked in flight to present a greater reflecting surface. ATIC's official comment was weather. Goose AFB was famous for unusual reports. In early UFO history someone had taken a very unusual colored photo of a "split cloud." The photographer had seen a huge ball of fire streak down through the sky and pass through a high layer of stratus clouds. As the fireball passed through the cloud it cut out a perfect swath. The conclusion was that the fireball was a meteor, but the case is still one of the most interesting in the file because of the photograph. Then in early 1952 there was another good report from this area. It was an unknown.
