Charles Thomas Philippe Ulm AFC (18 October 1898 — 3 December 1934) was a pioneer Australian aviator.
World War I
Ulm joined the AIF in September 1914, lying about his name and age to get in. He fought and was wounded at Gallipoli in 1915, and on the Western Front in 1918.
Charles Ulm was married twice. In 1919 he married Isabel Amy Winter. After divorcing his first wife, in 1927 he married Mary Josephine Callaghan.
Partnership with Charles Kingsford Smith
Ulm is best known for his partnership with Sir Charles Kingsford Smith, and was Kingsford Smith's copilot on many of his famous flights, including the 1928 first crossing of the Pacific in the Southern Cross. Ulm was the "business brains" in the partnership, and acquired the funding necessary for the journey. Ulm was also Kingsford Smith's partner in establishing Australian National Airways.
Later flights and disappearance
After the failure of Australian National Airways, Ulm bought one of the airline's Avro X aircraft for himself, and named it Faith in Australia. In this aircraft in 1933, Ulm set the speed record from England to Australia at 6 days, 17 hours and 56 minutes, and made several trans-Tasman flights.
In 1934, flying in Faith in Australia, Ulm carried the first official airmail from New Zealand to Australia, and the first official airmail delivery from Australia to Papua New Guinea.
Ulm established a new company in September 1934, Great Pacific Airways Ltd, intending to operate a San Francisco-Sydney air service. Ulm disappeared in December 1934, together with copilot G.M. Littlejohn and navigator/radio operator J.S. Skilling, on a test flight from Oakland, California to Hawaii in VH-UXY Stella Australis, an Airspeed Envoy. It is believed an unexpected tailwind and bad weather caused them to fly past the islands in the dark. The wind was about 35 knots from the south-southeast and the aircraft may also have been pushed north of the islands. At approximately 10 am local time on 3 December, after sending a series of Morse coded radio messages to Hawaii advising that they were lost and running out of fuel, the Envoy ditched into the sea. Despite an extensive and immediate search by aircraft and 23 naval ships, no trace of Stella Australis or her crew was ever found. Ulm had chosen not to carry a life raft on board, preferring to save weight and predicting that the aircraft would float for two days if it were forced to land on the water.
The plane had been customized by Airspeed to meet Ulm's own specifications; Airspeed's manager, Nevil Shute Norway, suggested in his autobiography that the internal cabin design may have contributed to the navigational problems, because the inexperienced navigator had to sit some distance from the pilot.
In 1978 he was honoured on a postage stamp issued by Australia Post depicting Ulm and the Southern Cross.
In November 2008 Qantas announced that it would be naming one of its Airbus A380's after Charles Ulm in recognition of his contribution to the aviation industry. This A380 (registration: VH-OQG) entered service on 3 November 2010.
