Red and white UFO in Indiana

Summary

A witness in Indianapolis, Indiana, reported an unidentified aerial phenomenon in May 1966. They observed a red and a white light at night moving southwest. The object appeared as a solid light, brighter than ordinary lights, and changed intensity, even flickering. It passed behind trees before disappearing over the horizon, accompanied by a low rumbling sound. The report was incomplete, so authorities requested additional details without success. The description did not allow for a conclusive evaluation, and the case remains unresolved.
