Pilot B. [sic] P. Davidson, who met with almost instant death when the aeroplane crashed, was about 35 years of age, and a son of Vice-Admiral Alexander Percy Davidson, D.S.O., who was in command of H.M.S. Cornwallis throughout the Gallipoli campaign, and retired in 1921, two years before his son came to Australia. The late pilot was a member of the Royal Naval Air Service during the war, most of his fighting being done in the Blimps that patrolled the English Channel. He was mentioned in despatches for his work during one raid on German submarines. He had evidently had but little experience with aeroplanes then, for when he came to Australia in 1923 he underwent a full course of flying at the Point Cook aerodrome, Victoria. He joined the R.A.A.F. in that State shortly afterwards, and was a flying member of the force until he came to Brisbane last March to join the ranks of pilots in the service of the newly-formed Queensland Air Navigation Ltd. He was one of the crew that flew the first ’plane north for the company, and he had been piloting its machines over the route since then. Members of the company in Brisbane were shocked by the news of his death last night. He was most popular with his co-pilots, all of whom regarded him as a most efficient flyer.
