May 12, 1949 —nr. Holloman AFB, NM
9:30 p.m. Astronomer Donald H. Menzel leaves Holloman AFB on Highway 70 for Alamogordo, New Mexico. Shortly after noticing the star Antares, he sees another fuzzy object in the sky nearer to the horizon. A second object appears three degrees to the south. Determining that the objects are not Castor and Pollux or reflections, Menzel watches them another 4 minutes. Both objects vanish abruptly. [Eberhart]
