6:35 p.m. USAF F-51 fighter pilot of 18th Fighter Bomber Group flying F-51 at 9,000 ft on 180° heading at 240 mph sighted 50 ft diameter silver object at 1 o'clock position moving to 3 o'clock at 1,000 mph at about the same altitude, which then started a steep climb, but at the top of the loop the object resumed a horizontal course (heading 360° or N) wavered momentarily, descended and disappeared into the haze which reached an altitude of about 7,000-8,000 feet.

6:35 p.m. Air Intelligence Information Report No. 52-81 describes the encounter between the pilot of an F-51 propellor- driven fighter bomber and a silver object estimated to be about 50 feet in diameter. The aircraft was assigned to the 18th Fighter Bomber Group. The pilot had flown 76 combat missions in WW2 (World War II). He was... flying on a heading of 180 degrees at an altitude of 9,000 feet; he first noticed the object at the one o'clock position. "By the time I called the object in as a bogie, it had moved to the 3 o'clock position and started a steep climb, which I assumed was the beginning of a loop, but at the vertical position in the loop, the object moved forward in its original course of travel (360 degrees) and wavered momentarily and then descended and disappeared into the haze which reached an altitude of approximately 7,000 to 8,000 feet." While the (F-51) airplane was traveling at only 240 mph, the UFO was estimated to be moving at 1,000 mph, first to the east and then changing to the north. It was at approximately the same altitude as the airplane during the 15-to-25-second-long sighting."
