A Tennessee witness at Knoxville reported watching a fast moving, disc-shaped object, according to testimony in Case 82433 from the Mutual UFO Network (MUFON) witness reporting database.
The witness was at work and looking through windows facing south at 4:05 p.m. on February 26, 2017.
“I saw a silver disc come zooming by heading from northeast to southwest almost directly towards McGhee-Tyson Airport, which is class B airspace at an estimated 350 mph and 3,000-3,500 feet,” the witness stated. “A few minutes later, I saw an airliner descending from the south to north on downwind leg of landing pattern for the airport at one-third the speed of object. I am ex-Navy, having served aboard a helicopter carrier and do have a private pilot's license.”
Tennessee MUFON Field Investigator Leonteen Connolly closed this case as an Unknown UAV.
No images or videos were included with the report, which was filed on March 1, 2017.
