Delta-shaped UFO spotted in Van Nuys

Summary

In May 1955, a witness in Van Nuys, California, reported seeing a silver, delta-winged object moving at high speed and performing rolling maneuvers in the sky. The sighting lasted four to five minutes, and the object disappeared directly overhead. Although initially considered a balloon or astronomical event, the investigation concluded it was likely a conventional jet aircraft. However, the witness's reliability was deemed poor, and there were no photos or radar confirmation of the object's identity.
