Un unidentified object observed in Yuma Arizona in 1961

Summary

In February 1961, an object was detected by radar in Yuma, Arizona, for almost two hours. The report describes an object that was slowly descending, losing altitude at a rate of around 300 feet per minute, and eventually fading away. Observers, including military personnel, were unable to visually identify it, which limited the conclusions. The only clear clue was that the object behaved similarly to a chaff drop, a substance used to deceive radar systems.

Although radar specialists considered it could be a chaff test, no definitive confirmation was found. The report was reviewed by multiple military offices, but no clear conclusion was reached. The object did not show characteristics of a balloon, aircraft, or astronomical body, and its unusual behavior generated doubts. Although equipment malfunction was not ruled out, the case remains unresolved, adding another mystery to the history of unidentified phenomena.
