Two of his airplanes were famous. The Breese named "Aloha" took 2nd place in the 1927 Dole Race from California to Hawaii. It was painted yellow and red. The "Pabco Pacific Flyer" was also a participant in the Dole Race, but crashed upon takeoff. During 1933-34 he moved to California and worked for Northrop Corporation as test pilot. He demonstrated the Northrop Navy fighter, and performed test flights for Fokker. In 1937 he worked for Bennett Aircraft Corp. as VP and test pilot.
He was the test pilot at North American Aviation when the P-51 Mustang was developed and was its first test pilot on October 26, 1940.When war came in 1939 he joined his squadron on a full-time basis, but in the spring of 1940, with the squadron ordered to France, he was ordered back to Rolls-Royce to resume test flying at Hucknall, liaising closely with the RAF. Harker was at Hucknall when, in April 1942, he received a telephone call from the CO of the RAF's Air Fighting Development Unit at Duxford, to tell him that they had acquired an Allison-engined Mustang and would he like to evaluate it? Having spent 30 minutes throwing the aircraft round the sky he reported that it closely resembled the Messerschmitt 109F, but with a Merlin 61 engine ought to prove much faster than that aircraft and the Spitfire V. The Air Ministry, however, wanted to put all the available Merlin 61s into the new Spitfire IX to combat the threat of the latest German fighter, the Focke Wulf 190, which was proving vastly superior to the Spitfire V in combat. There was therefore a good deal of concerted scepticism about Harker's observations. But he persisted and the first Merlin-engined Mustang flew in October 1942, giving the radical improvements in performance that he had predicted. News of the Merlin Mustang's performance spread like wildfire and was greeted as manna from heaven in Washington. Indeed, the Americans were the chief beneficiaries of Harker's initiative, since the new escort fighter enabled the USAAF to resume daylight bombing raids which had been discontinued, since the "invulnerable" B17 Flying Fortress had proved incapable of defending itself against the Luftwaffe's fighters.
Throughout the war Harker was involved in a variety of other projects for improving the performance of RAF aircraft. Improvements in superchargers increased the speed of the Spitfire; Merlins were put into the Whitley bomber; and - the greatest bomber success of all - the disastrous Vulture-engined Avro Manchester became the superlative Merlin-engined Lancaster. But the Mustang remains his supreme achievement. By the end of the war 15,582 of the aircraft had been built. Harker was appointed OBE and given the Air Efficiency Award (AE) for his wartime work.Harker pressed strongly for the American engine to be replaced by the Merlin and, after a good deal of official reluctance, largely from the Air Ministry, he got his way. The result was a transformation. The Mustang's top speed went from 390 mph to 440 mph and the range from 450 miles to as much as 2000 with various configurations of drop tanks. A great escort fighter had been born and ever afterwards Harker was known as "the man who put the Merlin in the Mustang."
While chief test pilot performed initial flight test in many aircraft, including the XP-47 Thunderbolt, XP-72 and XR-12 Rainbow. Recognized as outstanding pioneer in the art of engineering flight tests. Retired as Vice President, Sales, Republic Aviation in 1964.
Augustus Henry Orlebar was educated at Rugby and served as an Officer with 1st/5th Bedfordshire Regiment at Gallipoli in 1915 before transferring to the RFC for pilot training in 1916. From
After the First World War he served with the Aeroplane Experimental Station, Martlesham Heath before taking up a permanent commission with the RAF and at the same time relinquishing his commission as a Lieutenant in the Bedfordshire Regiment on
In December 1929 he became OC Flying Boat Development Flight, during which he set a new air speed record of 357.7mph and in May 1931 OC RAF High Speed Flight,which won the Schneider Trophy for Britain in 1929 and 1931 thus securing the trophy as a permamnet possession.
At the out break of the Second World War he held the appointment of Director of Flying Training and then joined the Air Staff, HQ Fighter Command in October 1940
On 22 Jul 1941 he became AOC, No 10 (Fighter) Group and at the time of his death he held the position of Deputy Chief of Combined Operations, which he attained on 2 March 1943.
