UFO seen by pilot in Las Vegas 1947

Summary

In 1947, an Air Force Reserve pilot reported a unidentified flying object moving at an estimated speed of 400 to 1000 miles per hour. The object left no visible trail, but remained in the sky for fifteen to twenty minutes. The pilot observed the object making a 180-degree turn with a radius of five to fifteen miles before heading back toward its point of origin. The sky was described as "almost cloudless," adding to the mystery of the sighting.

The report includes an ALC opinion suggesting the phenomenon could have been caused by a conventional flying object, though none is specified. It is compared to a fireball, a rare meteorological event, but the report notes that the curved trajectory and repeated direction do not match typical fireball behavior. In summary, the incident remains unexplained, with no anomalies ruled out.
