The Hawker Tornado was a British single-seat fighter aircraft design of World War II for the Royal Air Force as a replacement for the Hawker Hurricane.
 The planned production of Tornados was cancelled after the engine it was designed to use—the Rolls-Royce Vulture—proved unreliable in service.
 A parallel airframe with the Napier Sabre continued into production as the Hawker Typhoon.
The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and many other Allied countries before, during and after World War II.
 The Spitfire was built in many variants, using several wing configurations, and was produced in greater numbers than any other British aircraft.
 It was also the only British fighter to be in continuous production throughout the war.
 The Spitfire continues to be popular among enthusiasts; about 54 remain airworthy, while many more are static exhibits in aviation museums throughout the world.
Albert Aubrey (Aub) Koch, MBE (2 October 1904 – 21 June 1975) was a pioneering Australian military and civil pilot.
 He trained at Point Cook in 1926, and following graduation accepted a Short Service Commission in the Royal Air Force (RAF) as there were no places available in the Royal Australian Air Force (RAAF) at the time.
 After four years service in Egypt and Palestine, he returned to Australia and was commissioned into the Citizen Air Force, flying with No. 1 Squadron at Laverton, where he gained flying instructor qualifications.
 Soon after, he was employed by Guinea Airways as an aircraft captain, and spent five years in Papua and New Guinea (PNG), gaining fame as the rescuer of the Archbold expedition.
 Koch was transferred to the RAAF Active Reserve upon going to PNG.
 He joined Qantas a year before World War II broke out, employed predominantly on the Singapore route.
 He was unfortunate to be the captain of the only Qantas aircraft known to be shot down during that war, when the Short Empire flying boat "Corio" was lost off Timor ("Circe" disappeared in 1942, possibly also shot down, and "Corinna" was destroyed by enemy action on the water at Broome, Western Australia).
 Post war he was recruited by Lester Brain at the formation of Trans Australia Airlines (TAA), specifically to be Senior Pilot DC4 Skymaster.
 At 45, he retired from active flying to become Inspector of Safety and Accidents, TAA.
The Hawker Hurricane is a British single-seat fighter aircraft used by the Royal Air Force and many other Allied countries throughout the Second World War.
 Replaced by newer designs later on during the Second World War it has not survived as well as its contemporary the Supermarine Spitfire.
Western Air Command was the part of the Royal Canadian Air Force's Home War Establishment responsible for air operations on the Pacific coast of Canada during the Second World War.
 When Canada declared war against Germany in September 1939 the command consisted of only five squadrons.
 Four of them equipped with obsolete aircraft including a bomber squadron with aircraft from the Great War and there were no fighter aircraft at all for its only fighter squadron (113 Fighter Squadron was thus disbanded).
 With the Japanese threat after Pearl Harbor it grew rapidly and played a critical role in fighter and anti-submarine operations in Canadian and American waters during the Aleutian Islands Campaign.
 It was there that Squadron Leader K.A. Boomer of No. 111 Squadron shot down a Rufe fighter, the RCAF's only kill in the Pacific Theatre.
 On 7 July 1942 a Bristol Bolingbroke pressed home an attack on the Japanese Submarine Ro 32 the pilot F/Sgt.
 P.M.G. Thomas of No. 115 Squadron RCAF then led American Destroyers to sink the damaged submarine.
 By January 1943 Western Air Command had expanded to include many bomber, fighter and operational units under its control.
 By the end of the war the command would involve some twenty squadrons when the last units to join were added in 1943.
 These were the 163 Army Cooperation Squadron in March flying Bristol Bolingbrokes and Hawker Hurricanes, in May the 160 Bomber-Reconnaissance Squadron was added flying Cansos from Sea Island BC (before moving to Yarmouth NS in July) and the 166 Communication Squadron formed in September flying various types.
 In addition to the new squadrons, new aircraft types came on line replacing the command's remaining Supermarine Stranraers and Blackburn Sharks with Canso's and the Bolingbrokes and Beauforts with the Lockheed Ventura.
 Countless training missions and operational patrols bolstered the air activity over the coastal areas but there was not much action until RCAF Western Command was on the look out for General Kusaba's Fire Balloons that the Japanese called the Fūsen Bakudan Campaign.
 In February and March 1945, P-40 fighter pilots from 133 Squadron, Royal Canadian Air Force operating out of RCAF Patricia Bay (Victoria, British Columbia), intercepted and destroyed two fire balloons, On 21 February, Pilot Officer E. E. Maxwell While shot down a balloon, which landed on Sumas Mountain, in Washington State.
 On 10 March, Pilot Officer J. O. Patten destroyed a balloon near Saltspring Island, British Columbia.
 During another interception a Canso forced down a fire balloon which was examined at the army headquarters.
 Patrol activity was joined by the Operational Training Schools (OTS) operated by Number 4 Training Command of the BCATP.
 They were the No. 3 OTS flying the Canso and Catalina and No. 32 OTS with Ansons, Beauforts and Swordfish at Patricia Bay.
 In April, 1944 the No. 5 OTS Heavy Conversion unit stood up at Boundary Bay when 16 B-24 Liberators arrived fresh from American factories.
 By the end of September 1944 RCAF 5 O.T.U. had grown to sizeable force of some 87 aircraft including 38 B-24 Liberators, 35 B-25 Mitchells, 5 Bolingbrokes, 8 P-40 Kittyhawks and a single Norseman.
 With the end of the war in Europe these aircraft were joined by a number of Victory Aircraft Lancaster X bombers which were to be used to train the British Commonwealth's Very Long Range Bomber Tiger Force that would soon be sent to bomb the Japanese mainland from Okinawa.
 With the unconditional surrender of Japan the RCAF's Tiger Force bomber squadrons were disbanded before they flew overseas and the total draw down of the Western Air Command was suddenly undertaken.
 Within several months almost all the flying squadrons would be completely stood down.
Leslie Redford (Les) Clisby, (29 June 1914 – 15 May 1940) was an Australian fighter ace of World War II.
 Serving with the Royal Air Force (RAF), he was credited with sixteen aerial victories before being killed in action during the Battle of France.
 In a combat career lasting a matter of months, he was Australia's first ace of the war.
 Born in South Australia, Clisby joined the Royal Australian Air Force as a mechanic in 1935, but was later accepted for flying training.
 He graduated as a pilot in 1937, and chose to take a commission with the RAF.
 After arriving in Britain, he was assigned to No. 1 Squadron, flying the recently introduced Hawker Hurricane.
 Posted to France following the outbreak of World War II, he achieved his first aerial victory on 1 April 1940.
 Clisby became known as a highly aggressive fighter pilot, who threw himself into combat irrespective of the odds.
 In a five-day period, commencing on 10 May 1940, he was credited with destroying at least eight German aircraft.
 Awarded the Distinguished Flying Cross for these and earlier victories, he was himself shot down in flames on 15 May.
 He was buried in France.
The Hawker Hurricane was a British single-seat fighter aircraft designed and predominantly built by Hawker Aircraft Ltd.
 Some versions were built in Canada by the Canada Car and Foundry Co Ltd
Going Solo is a memoir by Roald Dahl, first published by Jonathan Cape in London in 1986.
 It is a continuation of his autobiography describing his childhood, "Boy".
 It tells about his voyage to Africa, describing the various strange people he meets.

The Hawker Hunter is a transonic British jet-powered fighter aircraft that was developed by Hawker Aircraft for the Royal Air Force (RAF) during the late 1940s and early 1950s.
 It was designed to take advantage of the newly developed Rolls-Royce Avon turbojet engine and the swept wing, and was the first jet-powered aircraft produced by Hawker to be procured by the RAF.
 On 7 September 1953, the modified first prototype broke the world air speed record for aircraft, achieving a speed of 727.63 mph .
The Hawker Hurricane is a British single-seat fighter aircraft of the 1930s–1940s that was designed and predominantly built by Hawker Aircraft Ltd for the Royal Air Force (RAF).
 Although overshadowed by the Supermarine Spitfire, the aircraft became renowned during the Battle of Britain, accounting for 60 percent of the RAF air victories in the battle, and served in all the major theatres of the Second World War.
