On 1 April 1918, along with other members of the Royal Flying Corps, Kingsford Smith was transferred to the newly established Royal Air Force. On being demobilised in England, in early 1919, he joined Tasmanian Cyril Maddocks, to form Kingsford Smith, Maddocks Aeros Ltd, flying a joy-riding Service mainly in the North of England, during the summer of 1919, initially using surplus DH.6 trainers, then surplus B.E.2s. Later Kingsford Smith worked as a barnstormer in the United States before returning to Australia in 1921. He did the same in Australia and also flew airmail services, and began to plan his record-breaking FLIGHT across the Pacific. Applying for a commercial pilot's licence on 2 June 1921 (in which he gave his name as 'Charles Edward Kingsford-Smith'), he became one of Australia's first airline pilots when he was chosen by Norman Brearley to fly for the newly formed West Australian Airways.
