February 24, 1950 — Datil, NM
7:30 p.m. USAF Cpl. Lertis E. Stanfield and other Holloman AFB Photographic Branch project staff at an observation post at Datil, New Mexico, take five photos (using a Cineflex camera with 3-inch focal length lens) of a circular, luminous white object that changes to red and green. Its angular velocity is greater than 0.5°/min in azimuth calculated by Lincoln LaPaz. The object moves in a smooth straight-line motion from about 8:00–9:30 p.m. to the west, blinking red and green. It disappears at high altitude. [Eberhart]
