Several USAF fighter pilots saw three round disc-shaped objects making evasive maneuvers. Ground radar tracking.

Three white saucers were observed by several male military witnesses at a military facility.

Ruppelt's account:

On the night of August 23rd, shortly before midnight, reports of a UFO began to come in from the Mt. Healthy GOC observation post northwest of Cincinnati. Almost simultaneously, Air Defense Command radar picked up a target in that area. A minute or two later the Forestville and Loveland GOC posts, also in Hamilton County, made sightings. Now, three UFO's, described as brilliant white spheres, swinging in a pendulum-like motion, were on the ADC plotting boards- confirmed by radar. All pretext of ignoring the UFO's was dropped and at 11:58P.M., F-84's of the Ohio Air National Guard were scrambled. They were over Cincinnati at 12:10A.M. and made contact. Boring in at 20,000 feet, at 100% power, they closed but the UFO's left them as if they were standing still.

The battle in the Cincinnati sector was on.

Almost every night more UFO's were reported by the GOC. Attempts were made to scramble interceptors but there were no more radar contacts and a jet interceptor without ground guidance is worthless.
