Saucer-shaped UFO sighted in Tucson in 1949

Summary

A witness in Tucson, Arizona, reported in 1949 the observation of a bright cylindrical object, the size of a city block, reflecting sunlight. The object was seen for 12 minutes, following a curved trajectory and making no noise. It was described as a sausage-like shape with no wings or fins, appearing to slowly rotate. Other witnesses confirmed the sighting, and although several conventional explanations were considered, the report concluded the object was unidentifiable. The lack of smoke, noise, or vapor trails, along with its unusual size and movement, created a mystery that remains in declassified files.
