VH-UMR was part of the first Central Australian Gold Expedition in search of Lasseter's Reef, which was a rich vein of gold that Harold Lasseter claimed to have found in the desert. No gold was found and Lasseter would perish alone in the desert after the rest of the expedition quit the search. The photo of VH-UMR may be at Alice Springs Townsite aerodrome or at Ilbpilla Soak, the advanced search base, where it crashed on August 9, 1930. Repaired, UMR was sold in New Zealand in 1934 as ZK-ADF. Photo from: State Library of New South Wales

The personal aircraft of the then Prince of Wales, the future King Edward VIII. He disposed of it in 1931. G-ABBS was sold to the British High Commissioner to Iraq and would remain in the region for the rest of its existence. Initially it remained G-ABBS with British owners in Iraq and Iran until it was sold in Iraq as YI-ABB in May 1935. It remained Iraqi registered until it ended up as a wingless instructional airframe in Beirut. Photo from: The Early Aviation Photograph Collection/The Museum of Flight

The Curtiss Falcon biplane family included the O-1, O-11 and A-3 of the US Army and the naval F8C / OC /O2C. The Falcon Mailplane was normally a single-seater but is seen here being demonstrated to the Dutch military as a two-seater. Several Curtiss planes were demonstrated at Rotterdam on 8 July 1930 and this visit to Soesterberg likely took place in the same month. The Curtiss Hawk fighter was selling to the Netherlands East Indies army which felt that it was much more reliable than the Fokker biplanes, and the Falcon does look sturdier than the Fokker C.V 320, on the right.
