The Cleveland National Air Show is an annual air show held on Labor Day weekend at Burke Lakefront Airport in Cleveland, Ohio. It was established in 1964 as an indirect successor to the National Air Races. The show includes stunt airplanes, modern fighters and alternates between the U.S. Navy Blue Angels and U.S. Air Force Thunderbirds every other year. The show typically runs from 9:00 a.m. to around 4:30 p.m. EDT. The show usually starts with smaller acts, and the Blue Angels or Thunderbirds perform last. Another regular attraction is the NASA Glenn Research Center, which usually has an exhibit located near the back of the show. There is usually some type of heritage or legacy flight, sometimes both.
