Colima-to-Guadalajara travelers photograph disc in four-image sequence — 1958

On an undocumented date in 1958, Javier Torres and Alejandro Dueñas were driving from Colima toward Guadalajara and photographing the surrounding landscape. A disc-shaped object flew above them and appeared in a sequence of four photographs. The surviving chronology does not preserve the exact location, time, duration, object behavior, camera, negatives, or what the witnesses said immediately afterward.
