UFO in Helena Montana 1957

Summary

In August 1957, a woman in Helena, Montana, observed four bright disc-shaped objects. Two appeared briefly and disappeared, then two more did the same. The witness, unable to identify the object, estimated they were about 200 feet away. The report concluded it was probably an aircraft, though other explanations were not ruled out. The object's description and behavior caused some confusion, as they didn't fit typical aircraft of the time.
