Gilbert Eric Douglas (1902–1970), pilot and air force officer, took part in Sir Douglas Mawson’s British, Australian and New Zealand Antarctic Research Expedition (BANZARE), which took the form of two ocean voyages conducted over the southern summers of 1929–30 and 1930–31. Melbourne- born, Douglas joined the Australian Air Corps in 1920 and transferred to the RAAF in 1921. He graduated as a Sergeant Pilot in 1927. In April 1929, he flew to the Northern Territory as part of a team looking for the crew of a plane called the Kookaburra, which had crashed while itself taking part in a search for aviators Charles Kingsford Smith and Charles Ulm. Douglas was recommended for the Air Force Medal for his part in the mission and later the same year was seconded to take part in the BANZARE voyages. Along with aviator Stuart Campbell, Douglas – and the Gypsy Moth seaplane he referred to as ‘our machine’ – played a significant role in the expedition’s scientific and exploratory activities, flying ahead of expedition ship Discovery to identify routes through the pack ice, identifying sites for landings, and making ‘flights for photographs – both cine and still’ with official photographer Frank Hurley and his thirty-pound cinema camera. In a paper published in 1932, Mawson acknowledged that ‘the aeroplane proved a most important factor in the prosecution of the geographical program. Its successful operation, at times under most difficult conditions, [owed] everything to the determination and skill of Campbell and Douglas’. In 1935 Douglas returned to Antarctica to search for the missing American explorer Lincoln Ellsworth and his pilot Herbert Hollick-Kenyon. Awarded the Polar Medal and Bar for his part in the BANZARE expedition, Douglas joined the navy’s Department of Air Maintenance and Research in 1949.
