Kirtland Air Force Base, New Mexico: Controllers watch egg-shaped object, radar tracks it

At 10:45 p.m. on November 4, 1957, CAA air traffic controllers R. M. Kaser and E. G. Brink saw a highly maneuverable, 15–20-foot egg-shaped object with a white light at its base circle over one end of Kirtland AFB in Albuquerque at 150–200 mph, then come down in a steep 30° dive as if landing on Runway 26, north of the tower; radar tracked part of this maneuver. The object then crossed the flight line, runways and taxiways toward the tower at about 50 mph and 20–30 feet above the ground, watched through 7x binoculars, until it neared the northeast corner of the flood-lit restricted Manzano Nuclear Weapons Storage Area and a B-58 bomber service site, where it hovered for 20–60 seconds. It headed east again at about 200–300 feet and suddenly shot up in a steep climb. Radar Approach Control tracked it on CPN-18 radar circling the Albuquerque Low Frequency Range Station; it disappeared at 10 miles, reappeared 20 minutes later to follow half a mile behind a departing USAF C-46 for 14 miles, and a hovering radar target later appeared over an outer marker for 90 seconds before fading. The case is discussed in the Condon report and by James E. McDonald, J. Allen Hynek and Martin Shough. The account follows the entry in George M. Eberhart's chronology UFOs and Intelligence (CUFOS) and the sources cited there; it is not an independent determination by From Beyond Space.
