UFO detected on radar in Maine 1956

Summary

In August 1956, a pilot and a radar observer in Maine reported an object that appeared on the radar screen as either two aircraft or one large aircraft. Despite the radar detection at 12 miles, the object was not visually spotted at just 4000 yards, which caused confusion. The object was estimated to be moving at over 500 knots and was tracked for three minutes. The pilot and radar observer noted discrepancies between their instruments, suggesting a possible equipment malfunction or an unusual explanation.

A limited investigation assigned to the case concluded it was likely an aircraft, though other possibilities were not ruled out. The data was insufficient for a definitive evaluation, and the report included no photos or additional testimonies. Despite good weather and visibility conditions, the object was not clearly identified, keeping the mystery around this sighting.
