Lieutenant General František Fajtl (20 August 1912 – 4 October 2006) was a Czech fighter pilot of World War II. He was a British Royal Air Force (RAF) squadron and wing commander and led a group of Czechoslovak fighter pilots who formed an air regiment under Soviet Air Force command, supporting the Slovak National Uprising in 1944. He was dismissed from the Czechoslovakian Air Force and was held in prison for 1,5 year without a trial after the Communists came to power in 1948, and was only fully rehabilitated after the Velvet Revolution in 1989. He wrote many autobiographical books about his wartime experiences, and was an inspiration for the 2001 film Tmavomodrý svět (Dark Blue World).
