White UFO seen in Indianapolis in 1967

Summary

In 1967, a civilian in Indianapolis spotted a white saucer-shaped object slowly ascending eastward. The observation lasted about two minutes, with no photos taken and no physical evidence found. Although a commercial airliner passed through the area, it reported nothing unusual. The reports mention temperature inversions at various altitudes, which might explain the object's appearance. Investigators concluded it could have been an aircraft, but the witness insisted on the object's unusual shape. This case is part of a series of similar reports in the region.
