Red and silver UFO seen in Indiana

Summary

A red and silver object with red and green lights was observed in Bluffton, Indiana, in March 1966. The witness saw it for three minutes as it moved silently from south to north. Although the lighting and flight pattern resembled a conventional aircraft, no sound was heard, creating some confusion. The description of the object and its behavior didn't fully match what would be expected from a typical plane, which caught the observer's attention.
