Goble came to national attention in 1924 when he and fellow RAAF pilot Ivor McIntyre became the first men to circumnavigate Australia by air, journeying 8,450 miles (13,600 km) in a single-engined floatplane.
[1] He earned the Distinguished Service Cross for his actions on 24 September 1916, when he engaged two enemy fighters near Ghistelles in West Flanders, "and brought one of them down on fire in a spiral nose-dive", according to the citation in The London Gazette.
[13][14] His unit supported the British Fifth Army as it bore the brunt of the German spring offensive, and he had to evacuate his airfield when it was shelled by advancing enemy artillery.
[21] He received a permanent commission as a squadron leader and honorary wing commander in the RAF on 1 August 1919, and was seconded to the Royal Australian Navy.
The permanent Australian Air Board was established on 9 November 1920, and recommended creation of the AAF as an independent branch of the armed services.
[23] The AAF came into being on 31 March 1921—the 'Royal' prefix being granted five months later—and Goble resigned his commission in the RAF the same day to transfer to the new service as a wing commander.
[26] Instead, according to RAAF historian Alan Stephens, the arrangement "almost inevitably fostered an unproductive rivalry" between the two officers,[23] which was "exacerbated by the personality differences between the pedantic, autocratic Williams and the cheerful, easy-going Goble".
[29] In October 1921, Goble was posted to Britain for a naval co-operation course; his place on the Air Board was taken by Squadron Leader Bill Anderson.
Goble developed a plan to establish a small seaplane base at Rushcutters Bay in Sydney, but Williams cancelled this shortly after he returned to Australia in February 1925 to resume the position of CAS.
[1] Raised to temporary air commodore, Goble took over as CAS for the second time between December 1932 and June 1934, while Williams attended the Imperial Defence College in London.
[1][36] The young air force was a small, close-knit organisation comparable to a flying club, although several pioneering flights were undertaken by its members.
[37] One of the most notable was made by Goble and Flying Officer (later Flight Lieutenant) Ivor McIntyre in 1924, when they became the first men to circumnavigate Australia by air, in a single-engined Fairey IIID floatplane.
The English-born McIntyre, who was lead pilot while Goble acted as commander and navigator, was also a World War I veteran of the Royal Naval Air Service.
[38] As they flew above Point Cook, twelve RAAF aircraft took to the air to escort them to their landing place at St Kilda Beach, where they were welcomed by a crowd of 10,000 people.
[2] Prime Minister Stanley Bruce called the expedition "one of the most wonderful accomplishments in the history of aviation", his government presenting Goble with a gift of £500, and £250 to McIntyre.
[2][39] Though the flight is still acknowledged as one of the most important in Australian aviation, the necessity for the Air Force chief to personally command such a journey has been questioned, suggesting that it was motivated by the one-upmanship that characterised the Williams-Goble relationship.
[2] Two years later Williams would make a three-month, 10,000-mile (16,000 km) round trip from Point Cook to the Pacific Islands, the first international flight undertaken by an RAAF plane and crew, amid similar suspicions.
[2][40] As Chief of the Air Staff at the outbreak of World War II, Goble planned the expansion and decentralisation of the RAAF to meet the needs of home defence and Australia's obligations in Europe, which included the transfer of No.
"[43] Prime Minister Robert Menzies had in any case been looking for a British officer to head the RAAF and confided to the UK High Commissioner, Sir Geoffrey Whiskard, that Goble's resignation was "undoubtedly very convenient".
[48] Charged with alcohol trafficking on the island of Morotai in 1945, Caldwell was found guilty and reduced to the rank of flight lieutenant; he left the Air Force soon after.
[51] Other senior RAAF commanders who were veterans of World War I, including Richard Williams, were also retired at this time, ostensibly to make way for the advancement of younger officers.
