Nov. 7, 1957
Edwin G. Leadford, 19, 10181 Katella Ave., was driving east "over the Katella overpass at the Santa Ana Freeway, a mile east of Disneyland"* at 12:10 a.m. when he saw a mysterious object in the sky to the northwest, the Mirror said.
According to news accounts, he stopped and took this picture, then the object vanished. He said that members of the "Garden Grove Ground Observer Post" also saw the object but did not report it to "the Air Defense Filter center in Pasadena."
Leadford seems to have had a difficult time getting anyone to take his photograph seriously. The Times never even bothered to report this incident, but the Mirror used the photo on a picture page.
*I didn’t grow up in Los Angeles, so I don’t know if there was a time when Katella went over the Santa Ana Freeway or if the original story is wrong.
