Summary

A U.S. Navy pilot reported a cigar-shaped object in the skies over Riverside, California, in February 1956. The object was observed for eight minutes, but its sudden movement of 30 degrees in a fraction of a second stood out. Initially thought to be an optical illusion caused by unusual contrails, the object's defined shape, symmetry, and color sparked continued curiosity. The pilot described a straight and level course, which didn't align with typical aircraft behavior.

The presence of five known aircraft in the area, which were leaving contrails, was a key factor in the official assessment. However, the object's movement and appearance didn't match conventional expectations. The pilot, deemed reliable, provided a detailed account of the event, including its color, shape, and abrupt motion. While no photos or radar data were recorded, the firsthand testimony and lack of a clear explanation added an air of mystery to the case.
