Trinity UFO Case

The Trinity UFO case is a crashed unidentified object story-conspiracy theory set in August 1945 near the Trinity test, where the first atomic bomb had been detonated five weeks prior. The legend was first published in 2003 and was widely publicized in a 2021 book by longtime ufologist Jacques Vallée and Paola Leopizzi Harris.

According to José Padilla and Remigio Baca, when they had been small boys and were working at Rancho Padilla in San Diego, Antonito, near San Antonio, New Mexico, they saw a bright light, accompanied by a crashing sound. According to their reports, they found a crashed device nearby, "in the shape of an avocado", with a protrusion at one end, manned by insectoids. According to them, the object was later removed by the US Army.

By 2024, demonstrated anachronisms and falsehoods in the legend led skeptical writer Brian Dunning to characterize the legend as "a literal hoax, made up by people who knew they were making it up".
