Three restored P-51 Mustang fighters perform a formation flyby at the Lloyd Air Museum airshow in Tennessee, June 7, 2014. Developed during World War II, the P-51 Mustang became one of the most celebrated American fighters of the era, prized for its speed, range, and agility. Aircraft like these are lovingly maintained by warbird preservation groups and continue to headline airshows across the country, keeping the history of American military aviation alive for new generations.
