The Horsemen Aerobatic Team 

They are the only 3 ship P-51 Mustang formation aerobatic team in the world, flown by some of the most famous and experienced Warbird pilots in the world. The mission of The Horsemen is to "bring greater interest to the world of historic aviation and to remind future generations of how these powerful machines helped the Allies change the outcome of World War II, the Korean War, and the Vietnam War.
Since their formation in 1994, The Horsemen have utilized the insignia of the grim reaper on a horse bearing a shield with an emblem of the P-51 on the front of it. Since the addition of Steve Hinton to the team, the logo has also been altered to have the emblem of the F-86. The imagery is meant to represent the Four Horsemen of the Apocalypse, though Ed Shipley is quoted as saying that the name was inspired by a Metallica song.
