November 2, 1957 — Canadian, TX  
3:30 a.m. Three miles west of Canadian, Texas, S/Sgt. Alfred A. Calvin and a civilian witness see a submarine-shaped object, red and white, about 40–60 feet long and about 10 feet high, at ground level. A figure is near the object holding a white flag. When he stops the car, a flash of light from the object coincides with the sudden failure of the headlights.[Eberhart]
