began his own aircraft consultancy there. Galland worked hard but continued flying, taking part in national air shows. In 1956, he was appointed honorary chairman of the Gemeinschaft der Jagdflieger, the Association of Fighter Pilots. Through this, he came into contact with contemporaries in Britain and America. In 1961, he joined the Gerling Group of Cologne who contracted Galland to help develop their aviation business. With business going well, Galland bought his own aircraft on 19 March 1962, his 50th birthday. The aircraft was a Beechcraft Bonanza, registered D-EHEX, which he named Die Dicke (Fatty). In 1969, he served as technical adviser for the film Battle of Britain, in which the character Major Falke is based on Galland. Galland was upset about the director's decision not to use the real names. While making the film, Galland was joined by his friend Robert Stanford Tuck. Galland also threatened to withdraw at a planned sequence involving him giving a Nazi salute to Göring. Tuck also wrote into the producers, urging them to reconsider; at one point Galland brought his lawyer to Pinewood Studios. In 1973, Galland appeared in the British television documentary series The World at War, in episodes four and twelve, "Alone (May 1940 – May 1941)" and "Whirlwind: Bombing Germany (September 1939 – April 1944)". Galland took part in many engagements throughout the 1960s and 1970s. In 1974, he was part of the remaining German General Staff that took part in the Operation Sea Lion wargame at Sandhurst in the United Kingdom, replicating the planned German invasion of Britain in 1940 (which the Germans abandoned after their failure in the Battle of Britain). In 1975, he was a guest at the RAF Museum Hendon, during the unveiling of the Battle of Britain Hall, where he was entertained by Prince Charles. In 1980, Galland's eyesight became too poor for him to fly and he retired as a pilot. However, he continued to attend numerous aviation events, to include being a periodic guest of the U.S. Air Force for their annual "Gathering of Eagles" program at the Air Command and Staff College at Maxwell AFB, Alabama, USA. On 16 October, he was reunited with two Merkel shotguns stolen by American soldiers after his capture in 1945. Galland had located them before and had tried to buy them back, only to be turned down, as they would be worth more after his death.
