The term ace (now commonly flying ace) was first used by French newspapers during World War I, describing Adolphe Pégoud as l'as ('the ace'), after he downed five German aircraft. When aircraft began to shoot or force down other aircraft, systems to count "air victories" were subsequently developed. The American qualification of five victories eventually became the standard, even though other air services had previously used differing figures.
