In October 1961, a silvery flattened disk hovered motionless over a local school fair for more than 30 minutes.

I saw an unidentified flying object in the fall of 1961 or 1962. I was 11 or 12 years old at the time, and I was attending a fall fair with my parents at my elementary school.  Several hundred people were in attendance at this fair.  There were numerous rides for the kids and there were plenty of colored flashing lights all over the place.  One of my friend's dad was an amateur astronomer and had set up his telescope for people to see the moon and the planets.
At some point, a UFO appeared out of nowhere.  It was a silvery flattened disk with 2 or 3 portholes on the side. It was not a shiny silver color but had a sort of dullness to it.  It remained completely motionless over the large field where the fair was in progress.  It had an oscillating glow between red and green.  I cannot recall how high the UFO was but you could see it fairly well with the naked eye.  Many people observed the UFO through the telescope.  When I looked through the telescope, I could see that it appeared to be fairly bright inside the UFO but I did not see any life or movement inside.  Some one placed a call to either the local police or to the Tennessee Air National Guard which was located just a few miles away from the school. Two (2) jets were scrambled, and you could hear them approaching very quickly.  As they approached, the UFO took off at a very oblique angle, no sound was made, and the departure was faster than you could blink your eyes.
I am now 62 years old, and I have never forgotten that night.  From time to time, I have tried to find information on the internet about this incident but without success.
Witness indicates that the date of the sighting is approximate.  PD
