Red UFO with a glowing antenna

Summary

A 1961 UFO case describes a red object moving in circles with a bright antenna. Seen by seven people, including amateur astronomers, for 20-30 minutes. The object would stop, move north, and return. Through binoculars, it resembled Mars but had an antenna emitting white sparks like a "Fourth of July sparkler." Witnesses ruled out conventional explanations like balloons or aircraft. The Air Force classified it as "unidentified."
