Kirtland tower sighting
At about 10:45 p.m. on 4 November 1957 two air-traffic controllers in the Kirtland AFB tower in Albuquerque watched a dark object descend at the end of Runway 26, hover within 3,000 feet of the tower and climb away; approach radar confirmed a target.

The sceptical view
Blue Book concluded the controllers misidentified a conventional aircraft, perhaps a private pilot who had tried to land at the wrong field; the Condon study later reviewed the case and found no reason to overturn that.
