Hovering, round noiseless aircraft with round light in center hovering low over my car.

Refering to Ft Smith Ark sighting in Aug. of 66 or 67. Made headlines, seen by hundreds of people. I saw it within 50 ft. A large round aircraft slowly glided over my parked car and hovered motionless, turned on very bright light in center for 10- 15 seconds, light went out & craft was nearly out of sight in a second. All other witnesses reported seeing small objects, this was approximately 40-60 feet in diameter. They were three other people with me, I the only one left at 76. I have the newspaper clippings and thought I would share this with you.
