UFO detected by radar in Northern California

Summary

In August 1957, an aircraft detected an unusual object on radar. The object appeared as a "skinpaint," a clear and defined signal, distinguishing it from typical radar objects. The object remained in contact for over an hour, making sudden and rapid movements that confused observers. At one point, the object rapidly distanced itself and then reappeared, flying parallel to the aircraft. Despite efforts, no visual contact was made. Officers considered the possibility of anomalous propagation, an atmospheric phenomenon that can create false radar signals. This case was significant because it was the first time a "skinpaint" was recorded instead of a typical IFF (Identification Friend or Foe) signal.

The report was prepared by military personnel and classified as unclassified, allowing its study today. The nature of the object remains unresolved, but the fact that such a clear and persistent signal was recorded suggests it was not a common phenomenon. The data from this incident are valuable for understanding how radars can capture unconventional objects and how to interpret those signals.
