A Delta McDonnell Douglas MD-88 en route from Orlando to Cincinnati made an emergency landing in Knoxville after pilots reported smoke coming from the plane.
The five crew and all the passengers put on oxygen masks but removed them on landing as a ground crew inspected the outside of the plane. Emergency services did not see smoke or fire.
The unplanned landing was uneventful. A replacement flight was provided for to accommodate 52 passengers. There were no injuries, but there was a discrepancy of the number of people reported aboard.
