Unidentified flying object detected by radar at Selfridge AFB in 1950

Summary

In March 1950, radar personnel at Selfridge Air Force Base in Michigan recorded an unidentified object displaying unusual movements. According to the reports, the UFO appeared on two different radar screens, maintained a fixed position for several minutes, and then moved rapidly in multiple directions. Operators, including Lieutenant Mattson, observed the object descending vertically over the base, appearing as a bright yellow light. Technical analyses concluded that it was neither atmospheric interference nor a known phenomenon, raising interest in the possibility of an unknown object. The collected data included abrupt altitude and speed changes, surpassing what would be possible for any conventional aircraft of the time.

The reports highlight that the UFO was observed simultaneously by two different radar systems, increasing the credibility of the sighting. Experts reviewed the data and concluded there was no conventional explanation for the object's behavior. Additionally, the UFO remained stationary in space for two minutes, an unusual feat for any known aircraft. The records showed the object moving at speeds exceeding those of the fastest aircraft of the era, sparking debates about its nature. Despite investigations, no satisfactory explanation was found, leading to the case being classified as an unidentified phenomenon.
