The missing man formation is an aerial salute performed as part of a flypast of aircraft at a funeral or memorial event, typically in memory of a fallen pilot, a well-known military service member or veteran, or a well-known political figure. The planes fly in a formation with a space where one plane should be, symbolizing the person's absence. Missing man formations are also used in motorsport in memory of a recently deceased driver and in American football in memory of a recently deceased player. Description Several variants of the formation are seen. The formation most commonly used in the United States is based on the "finger-four" aircraft combat formation composed of two pairs of aircraft. The aircraft fly in a V-shape with the flight leader at the point and their wingman on their left. The second element leader and his wingman fly to their right. The formation flies over the ceremony low enough to be clearly seen and the second element leader abruptly pulls up out of the formation while the rest of the formation continues in level flight until all aircraft are out of sight. In an older variant, the formation is flown with the second element leader position conspicuously empty. In another variation, the flight approaches from the south, preferably near sundown, and one of the aircraft will suddenly split off to the west, flying into the sunset. In all cases, the aircraft performing the pull-up, split off, or missing from the formation is honoring the person (or persons) who has died, and is representing their departure. Examples Origins In 1936, King George V received the first recorded flypast for a non-RAF funeral. The United States adopted the tradition in 1938 during the funeral for Major General Oscar Westover with over 50 aircraft and one blank file. By the end of World War II, the missing man formation had evolved to include the pull-up. In April 1954, United States Air Force General Hoyt Vandenberg was buried at Arlington National Cemetery without the traditional horse-drawn artillery caisson. Instead, Vandenberg was honored by a flyover of jet aircraft with one plane missing from the formation. Aerial salutes On January 31, 1986, four NASA T-38s flew the missing man formation over Johnson Space Center to honor the STS-51L Challenger crew. On November 26, 1999, four Air Force F-16s flew the missing man formation over Kyle Field to honor the 12
