UFO detected by radar at Misawa, Japan

Summary

In April 1965, officers at Misawa Air Base in Japan recorded multiple radar contacts with unidentified objects. The targets appeared on surveillance and precision radar screens without confirmed visual contact. The objects moved at speeds between 150 and 200 knots, and sometimes approached the airfield before disappearing. Despite considering possibilities like birds, insects, or weather effects, no physical evidence or photographs were found. Reports noted that the targets didn't follow a clear pattern but often converged toward the runway or a nearby antenna. The most plausible explanation was anomalous radar propagation, though other causes weren't ruled out.

The investigation concluded that anomalous radar propagation was the most likely cause of the returns, as the targets weren't visible and didn't match other radars. Incidents occurred over several days, with multiple targets appearing simultaneously. Despite efforts, no physical evidence was found, and no mission explained the phenomena. Officers noted that the targets behaved unusually, with speeds and directions not matching conventional objects.
