What Zamora reported is still under intense dispute decades later. He says he saw a sedan-size, shiny object on a hilltop. Once he got closer on foot, the object began making loud noises. Zamora backed away but saw the UFO rise into the sky and speed away until it disappeared.

The UFO sighting — which is still unexplained despite investigators' belief that Zamora told the truth — was investigated by the United States Air Force as a part of Project BLUE BOOK, which recorded 12,618 sightings of strange objects between 1947 and 1969. The Central Intelligence Agency also assisted in analyzing the sightings.
