The Walsh Brothers Flying Boats were aircraft that were used during World War I to provide training to pilots in New Zealand prior to their enlistment into the Royal Flying Corps.

Walsh brothers

Brothers Leo and Vivian Walsh built a Howard Wright biplane in 1910 and flew it on 5 February 1911. In August 1911, the aircraft crashed but it was later rebuilt by the brothers and converted into an entirely new aircraft, with a streamlined nacelle positioned between the wings, which had a swept outer bay, while the canard was replaced by a conventional tailplane.^{[citation needed]}

The New Zealand Flying School

During 1914 the Walsh brothers constructed a two-seat flying boat similar to a Curtiss design. The war broke out in August 1914, and the Curtiss-based design was modified with dual controls to become a trainer and first flown on 1 January 1915. In October 1915, the brothers founded the New Zealand Flying School to train men for the Royal Flying Corps. The first class of three included the fighter ace, Keith Caldwell. Classes were always small but, in contrast to overseas training, comprehensive.^{[citation needed]}

Evolution of the Curtiss design

Due to the difficulties in obtaining suitable training aircraft, the Walsh brothers decided to build their own trainers, initially based on the Curtiss pattern. Over the next four years they produced a series of four flying boat designs, evolved from, but bearing little resemblance to, the original Curtiss model. The last of the Walsh Brothers designs, the Type D of 1919, was an aerodynamically and hydrodynamically advanced machine, with a powerful Beardmore engine.^{[citation needed]}

Sale to NZPAF

The flying school struggled to gain clients after the war, and all assets of the flying school were acquired for the New Zealand Permanent Air Force (NZPAF) in 1924. All Walsh brothers flying boats had been made for the use of the school, not for sale, and were transferred to the NZPAF; however, the NZPAF had a landplane training programme based upon the Avro 504K and had no use for the flying boats. The survivors are believed to have been burnt on the Auckland waterfront, however there are "lost treasure" stories that these and some of the other machines used by the flying school are stored on a defence force base at Devonport in tunnels bricked up after the Second World War.^{[citation needed]}
