Airport workers only found the wreck site and the dead pilot after another plane spotted it it while taxiing.
It’s thought the single engine Cessna 172 crashed and burned during heavy fog and may have been there for as long as six hours.
CNN reports the airport and control tower are fully staffed 24/7 and aren’t sure why no one saw the plane.
The FAA confirmed the aircraft was registered to the Windsor Flying Club in Ontario, Canada.
Investigators aren’t sure yet if the pilot tried to make any distress calls or had any contact controllers before the crash.
National Transportation Safety Board spokesman Peter Knudson told The Tennessean "we will want to understand what the circumstances were that caused it to go undiscovered for so long."
The crash closed one runway but three others remained open and commercial traffic was not held up at any point.
