1957 Kirtland Sighting: A 'Possible Aircraft' Case Revisited by Blue Book, the Condon Report, and James E. McDonald

To the point

R. M. Kaser and E. G. Brink, two Civil Aeronautics Administration controllers at Kirtland AFB, saw a white light and a small, egg-shaped object hover very low, briefly radar‑confirmed, follow a C‑46 for about 14 miles, then fade into the clouds; Capt. Shere of Ent AFB, for Project Blue Book, concluded the witnesses were reliable but the craft could be a private plane mistaken for a landing, a view echoed by the Condon Committee, and James E. McDonald later revisited the witnesses, who reportedly found those conclusions amusing.

Kirtland AFB UFO sighting - Wikipedia

At Kirtland Air Force Base in late 1957, Civil Aeronautics Administration controllers R. M. Kaser and E. G. Brink observed a white light and a dark, egg-shaped object with radar contact that hovered, descended, and tailed a C-46 for about 14 miles before fading, a finding by Capt. Shere of Ent AFB that it was likely a private aircraft mislanding—an interpretation echoed by the Condon Committee—and, years later, James E. McDonald re-interviewed the witnesses who reportedly found those conclusions amusing.
