The Socorro Incident (Lonnie Zamora)

On April 24, 1964, Socorro, New Mexico police officer Lonnie Zamora broke off a traffic pursuit to investigate a roar and flame in the desert. He reported a white egg-shaped object on the ground, two small figures beside it, and its loud departure. Investigators documented burned brush and landing impressions. Project Blue Book listed the case as unexplained, and J. Allen Hynek considered it one of the most credible reports in the files.

Zamora was chasing a speeding car south of Socorro when he heard a roar and saw flame descending in the distance, in an area with a dynamite shack he thought might have exploded. Driving toward it, he saw a shiny object he first took for an overturned car, with two figures in white coveralls beside it, described as small, "possibly children." Approaching on foot, he heard a loud roar, saw flame beneath the object, and took cover as it rose. He described a smooth, legged, egg-shaped craft with a red insignia, which departed at speed and in silence after the initial roar.

Zamora radioed for backup. Sergeant Sam Chavez of the state police arrived within minutes and found Zamora shaken. The two documented burning and smoldering brush and four wedge-shaped ground impressions.

Zamora was a five-year veteran of the Socorro police force with a reputation for reliability. Chavez was the first corroborating responder. The FBI (an agent happened to be nearby), the Army, and Project Blue Book, with Hynek visiting Socorro twice, all investigated.

Physical traces: the landing impressions and burned vegetation, photographed and measured. No radiation above background was found. There were no other confirmed eyewitnesses to the object itself, though a tourist family's secondhand account of a low-flying object was reported. No photographs of the craft exist.

Blue Book classified Socorro as unknown. It was one of the cases the Air Force could not explain and did not attempt to argue away. Hynek wrote that Zamora was an excellent witness and the case a puzzle.

The leading skeptical theory holds the case was a hoax by New Mexico Tech students targeting Zamora, a theory supported by a letter from Linus Pauling's papers and later statements attributed to a former college president, but never confirmed with named participants or physical mechanics. Others proposed a test of a lunar lander prototype, which records do not place in Socorro that day. Philip Klass argued the town invented a tourist attraction, a theory even other skeptics discount. Proponents note that no explanation has ever accounted for all the documented traces and Zamora's consistent testimony. The case remains officially unexplained.
