IncidentLonnie Zamora / Socorro Incident (24 April 1964)
Socorro, New Mexico police officer Sgt. Lonnie Zamora witnessed an egg-shaped object on the ground with two figures in white coveralls beside it; the landing site preserved four symmetric burn-marked impressions and scorched vegetation.
What's documented
At approximately 17:45 on 24 April 1964, Sgt. Lonnie Zamora of the Socorro Police Department was pursuing a speeding vehicle south on US 85 when he heard a roar and saw a flame in the sky. He diverted to investigate a possible dynamite shed explosion. He approached a shallow arroyo and saw a shiny, oval craft standing on legs, with two small figures in white coveralls beside it. The figures returned to the craft, which then lifted off with a roar and departed silently to the southwest. FBI Special Agent Arthur Byrnes of the Albuquerque field office arrived within hours; Project Blue Book chief Maj. Hector Quintanilla arrived the next day. The site contained four wedge-shaped depressions, burned greasewood, and a charred juniper. Project Blue Book classified the case as ‘unidentified’ — one of 701 cases in that category at program closure.
