On December 1956 two USAF jet pilots were practicing ground radar positioned intercepts on each other in the vicinity of .
During one run, the intercepting pilot picked up a strange radar blip from an unknown object in the sky. From the blip's size — one eighth of an inch high and three-eighths of an inch wide. — the UFO was estimated at least as large as a B-29 four-engine bomber. Radar showed it to be twenty miles away. 30 degrees to the pilot's left.
Pilot called the GCI [Ground Control Intercept] site . Received permission to determine the nature of the source of the radar return.
As he headed toward the UFO, the jet's instruments showed he was closing at a speed of six to seven hundred knots. (Approximately 720 to 840 MPH.) At eight miles, a round object appeared exactly where radar showed it. Later calculations indicated it was at least 200 feet in diameter. Probably nearer 350.
By this time the jet's radar had locked onto the UFO and was automatically guiding the plane toward the object. Suddenly the radar was jammed by a strong interference. Using anti-jam procedure, the pilot switched frequency. For ten seconds this eliminated the mysterious interference pulses. Then they began again. But the pulsations were not strong enough to break radar lock-on and jet held its course.
The jet closed to within five nautical miles of the object and could not close further. When the pilot was closest to the unidentified object, it appeared to make a shallow left turn. It had the appearance of being circular on the bottom.
After this, the UFO speeded up so swiftly that the jet's radar could not get an accurate reading.
The object was moving up and away from 1,500 to 1,800 knots. (1,800 to 2,160 MPH.)
Immediately after the pilot reported the UFO and landed, his jet was tested by another Air Force pilot. All equipment, including radar, operated correctly. The aircraft was then checked by ground personnel. Again, all items were satisfactory,
