Before Germany could mount Operation Sea Lion, a cross-channel invasion of the British Isles, it needed to have complete air superiority over the invasion fleet. Because of the Luftwaffe‘s greater numbers and modern aircraft, German military leadership believed this could best be accomplished by defeating the Royal Air Force in air-to-air combat.
The Royal Air Force had been conserving their limited numbers of pilots and aircraft up to this point in the war. Germany’s plan was to send its bombers against targets that the R.A.F. would be forced to defend. The escorting Messerschmitt Bf 109s (also referred to as the Me 109) would then shoot down the Boulton Paul Defiants and Bristol Blenheims. But the Hawker Hurricanes and Supermarine Spitfires were up to the task. While the Hurricanes went after the Luftwaffe’s Dornier 17 and Heinkel He 111 bombers, the Spitfires engaged their Bf 109 fighter escorts.
Britain used a system of radar-directed ground control of its fighter squadrons. The result was that, although both sides lost about the same number of aircraft, the Battle of Britain was a decisive victory for Great Britain. Germany was forced to give up on its plans for an invasion of England.
During a speech the House of Commons, 20 August 1940, Prime Minister Winston Churchill referred to the pilots of Fighter Command when he said,
“The gratitude of every home in our Island, in our Empire, and indeed throughout the world, except in the abodes of the guilty, goes out to the British airmen who, undaunted by odds, unwearied in their constant challenge and mortal danger, are turning the tide of the world war by their prowess and by their devotion. Never in the field of human conflict was so much owed by so many to so few.”
Ever since, the Royal Air Force has been known as “The Few.”

Reginald Joseph Mitchell born 20 May 1895 at Butt Lane, a suburb of Kidsgrove, Newcastle-under-Lyme, Staffordshire, England. He was the first of three sons of Herbert Mitchell, a school teacher, and Eliza Jane Brain Mitchell, whom some sources also describe as a teacher.
Mitchell attended the Higher Elementary School on Queensbury Road, which provided a “semi-technical and more advanced education” in Normacot, and then Hanley High School, Stoke-on-Trent, leaving at the age of 16. He found work as a Premium Apprentice at the Kerr Stuart & Co., Ltd., locomotive engineering works in Fenton, where he was employed in the drafting room. Mitchell attended night school, studying mathematics, mechanics and technical drawing.
In 1917 Mitchell was employed as assistant to Hubert Scott-Paine, owner of the Supermarine Aviation Works, Ltd., at Southampton, Hampshire. (Scott-Paine is known for his hard-chine motor torpedo boat designs.) Supermarine concentrated on building flying boats and amphibians.
Reginald Joseph Mitchell married Miss Florence Dayson, a school teacher 11 years his senior, 22 July 1918, at Cheadle, Staffordshire, England. They would have a son, Kenneth Gordon Brunt Mitchell, born 6 November 1920.¹
Mitchell was promoted to Chief Designer at Supermarine in 1919, and Chief Engineer, 1920. Mitchell’s first complete airplane design was the Supermarine Commercial Amphibian of 1920.
Supermarine had been involved in the Coupe d’Aviation Maritime Jacques Schneider (the Schneider Trophy races) since 1919, when the company entered its Sea Lion biplane flying boat. The Sea Lion II amphibian won the race at Naples, Italy, in 1922.
For the 1925 Schneider race, Mitchell designed a new monoplane seaplane, the Supermarine S.4, G-EBLP, which was powered by a liquid-cooled Napier Lion VII “broad arrow” W-12 engine. The S.4 was damaged prior to the race, which was won by Jimmy Doolittle with the Curtiss R3C-2 racer.
During this period, Mitchell also designed the Supermarine Southampton biplane flying boat for the R.A.F. He was named Technical Director in 1927.
For the 1927 race, Mitchell designed the Supermarine S.5., which featured a monocoque duralumin fuselage. Three S.5s were built, N219, N220 and N221. Flown by officers of the Royal Air Force High-Speed Flight, the S.5s took first and second place.
Two Supermarine S.6 seaplanes, N247 and N248, were built for the 1929 Schneider race held at Calshot, not far from the Supermarine Works. These airplanes were powered by the new Rolls-Royce R liquid-cooled V-12.
called “Mitch” by officers of the High-Speed Flight
For his work on the Supermarine racers, His Majesty George V, King of Great Britain, Ireland and the British Dominions Beyond the Seas, Emperor of India, appointed Reginald Joseph Mitchell a Commander of the Most Excellent Order of the British Empire (C.B.E.).
CENTRAL CHANCERY OF THE ORDERS OF KNIGHTHOOD.
St. James’s Palace, S.W. 1,
1st January, 1932.
The KING has been graciously pleased to give orders for the following promotions in, and appointments to, the Most Excellent Order of the British Empire :—
To be Commanders of the Civil Division of the said Most Excellent Order :
Reginald Joseph Mitchell, Esq., A.M.I.C.E., F.R.Ae.S. Director and Chief Designer, Supermarine Aviation Works (Vickers) Limited. For services in connection with the Schneider Trophy Contest.
In August 1933, Mitchell underwent a routine medical examination, which resulted in a diagnosis of rectal cancer. Treatment options were very limited in the 1930s. He underwent a major surgical procedure which included a permanent colostomy. It can be assumed that Mitchell suffered from illness, significant pain and fatigue, but he continued working.
R.J. Mitchell decided that if he learned to fly, he would better understand the airplanes he was designing. He began flight lessons in December 1933, just a few months after the cancer surgery. He was awarded his pilot’s license in July 1934.
During this period, Mitchell worked on the single engine Supermarine Walrus and twin engine Scapa and Stranraer flying boats. The Walrus first flew 21 June 1933, with deliveries to the Royal Australian Air Force in 1935, and to the Royal Air Force in 1936. The Walrus was used extensively in air-sea rescue operations during World War II, saving more than 1,000 airmen.
In 1936, Mitchell began working on the Type 316 four-engine heavy bomber. Two prototypes were ordered but not completed. They were lost when the Supermarine factory was bombed in 1940.
In October 1936, Mitchell won a landing competition award from the Hampshire Aero Club. His trophy is now in the collection of the Solent Sky Museum.
R.J. Mitchell is, without question, best known as the designer of the Vickers-Supermarine Type 300, a private venture, built to meet an Air Ministry requirement for a new single-place, single-engine interceptor for the Royal Air Force. The prototype, K5054, flown by Vickers Aviation Ltd.’s Chief Test Pilot, Captain Joseph (“Mutt”) Summers, made its first flight at 4:35 p.m., Thursday afternoon, 5 March 1936. Landing after only 8 minutes, Summers is supposed to have said, “Don’t change a thing!”
The Air Ministry ordered the Type 300 into production as the Spitfire Mk.I before K5054’s first flight, with an initial order for 310 airplanes. The first production fighter was delivered to the Royal Air Force 4 August 1938. Between 1938 and 1948, 20,351 Spitfires were built in 24 variants.
The Spitfire became a legendary fighter during the Battle of Britain. It is a prime example of the saying that “if an airplane looks good, it will fly good.” And the Spitfire is a beautiful airplane. It was well armed, fast and maneuverable, and performed well at high altitudes. Reportedly, Luftwaffe pilots felt that there was greater dignity in having been shot down by a Spitfire than by a Hawker Hurricane, or Bolton Paul Defiant. The BBC reported, “It is a plane that came to symbolise British spirit and freedom from aggression. A bird of paradise, and it is still recognised in every country throughout the world.”
In October 1936, Mitchell won a landing competition award from the Hampshire Aero Club. His trophy is now in the collection of the Solent Sky Museum.
Cancer recurred in 1936. Mitchell was hospitalized in February 1937. This time he stopped working, though he would often go to the airfield to watch his Spitfire being tested. He travelled to Vienna, Austria for medical treatment in April, but returned home in May.
Reginald Joseph Mitchell, C.B.E., F.R.Ae.S., died at his home on 11 June 1937. His ashes were interred at the South Stoneham Cemetery, Hampshire, England.
In 1942, a popular film, “The First of the Few”, dramatized Mitchell’s life. The movie was produced, directed and starred Leslie Howard as Mitchell, and David Niven as a composite pilot character. It was released in the United States under the title, “Spitfire,” 12 June 1943, six years after the death of Mitchell, and less than two weeks after Leslie Howard was killed when BOAC Flight 777 was shot down by Luftwaffe fighters over the Bay of Biscay.
¹ Gordon Mitchell served aboard air-sea rescue launches in the Royal Air Force Volunteer Reserve, 1942–1944. (Many of these had been designed by Hubert Scott-Paine.) He was commissioned as a flying officer in September 1944 and served as a meteorological officer until 1947. Dr. Gordon Mitchell, Ph.D. worked at the University of Reading, National Institute for Research in Dairying, from 1952 until 1985. Dr. Mitchell died 24 November 2009.
5 March 1936: At 4:35 p.m., Thursday afternoon, Vickers Aviation Ltd.’s Chief Test Pilot, Captain Joseph (“Mutt”) Summers, took off on the first flight of the Vickers-Supermarine Type 300, K5054, prototype of the legendary Supermarine Spitfire, at Eastleigh Aerodrome, Southampton, England. Landing after only 8 minutes, Summers is supposed to have said, “Don’t change a thing!”
The Vickers-Supermarine Type 300 was a private venture, built to meet an Air Ministry requirement¹ for a new single-place, single-engine interceptor for the Royal Air Force. The airplane was designed by a team led by Reginald Joseph Mitchell, C.B.E., F.R.Ae.S., and was built at the Supermarine Aviation Works, Southampton, Hampshire, England.
R.J. Mitchell was famous for his line of Schneider Trophy-winning and world record-setting Supermarine racers of the late 1920s and early 1930s, the Supermarine S.4, S.5, S.6 and S.6B.² Mitchell was appointed Commander of the Most Excellent Order of the British Empire (Civil Division) (CBE) in His Majesty’s New Year’s Honours, 2 January 1932, for “services in connection with the Schneider Trophy Contest.”
The Vickers-Supermarine Type 300 was 29 feet, 11 inches (9.119 meters) long, with a wingspan of 36 feet, 10 inches (11.227 meters) and overall height of 12 feet, 8 inches (3.861 meters). The wings had a distinctively ellipsoid shape, area was 242.0 square feet (22.48 square meters). Its empty weight was 4,082 pounds (1,151.6 kilograms) and loaded weight was 5,359 pounds (2,430.8 kilograms).
K5054 was powered by a right-hand tractor, liquid-cooled, supercharged, 1,648.9-cubic-inch-displacement (27.04-liter) Rolls-Royce Merlin C (“ramp head”) single overhead camshaft (SOHC) 60° V-12 engine, serial number C9 (Air Ministry serial number A111,139), which had a Normal Power rating of 1,029 horsepower at 2,600 r.p.m. at an altitude of 11,000 feet (3,353 meters), with +6 pounds per square inch boost (0.41 Bar). The engine turned aan Airscrew Co., Ltd., Watts-type two-bladed, fixed-pitch, compressed wood propeller through a gear reduction drive (possibly 0.420:1). (K5083, the prototype Hawker Hurricane, was also equipped with a Merlin C.) An improved 1,035 horsepower Merlin F engine, serial number F21 (Air Ministry serial number A115,73 ), was later installed.
Interestingly, Rolls-Royce discovered that using exhaust stacks to direct the flow of gases rearward provided an additional 70 pounds of thrust, an increase of 7% over that provided by the propeller alone. Later testing of K5054 with “fish tail” exhaust stacks increased its top speed to about 360 miles per hour (579 kilometers per hour).
The Type 300 had a cruise speed of 311 miles per hour ( kilometers per hour) at 15,000 feet (4,572 meters), and could reach that altitude in 5 minutes, 52 seconds. maximum speed of 349 miles per hour (562 kilometers per hour) at 16,800 feet (5,121 meters). The prototype had a service ceiling of 35,400 feet (10,790 meters).
A report summarizing the flight testing of K5054 stated, “The aeroplane is simple and easy to fly and has no vices.” Visibility was good, the cockpit was comfortable, and it was a stable gun platform.
On 22 March 1937, K5054’s engine lost oil pressure and the pilot made a belly landing on Marlesham Heath. The Spitfire was damaged, but was repaired and returned to service.
The prototype Spitfire stalled on landing at RAE Farnborough, 4 September 1939. After several bounces on the runway, it nosed over. The pilot, Flight Lieutenant Gilbert Stanbridge (“Spinner”) White, was severely injured. He died 9 September.
K5054 was disassembled and scrapped.
The Air Ministry ordered the Spitfire Mk.I into production before K5054’s first flight, with an initial order for 310 airplanes. The first production fighter was delivered to the Royal Air Force 4 August 1938. Between 1938 and 1948, 20,351 Spitfires were built in 24 variants.
Captain Joseph Summers, C.B.E., was born 10 March 1904. He was the older brother of Group Captain Maurice Summers, who was also a test pilot for Vickers. In 1922, he married Miss Dulcie Jeanette Belcher at Sculcoates, Yorkshire. They would have several children.
In 1924, Summers received a short-service commission as an officer in the Royal Air Force. He trained as a pilot with No. 2 Flight Training Squadron, at RAF Duxford. He was hospitalized for six months, which delayed his training, but he graduated in 1924 and was assigned to No. 29 Fighter Squadron. Summers was considered to be an exceptional pilot, and with just six months’ operational experience, he was assigned as a test pilot at the Aircraft and Armaments Engineering Establishment (A&AEE) at RAF Martlesham Heath. He remained there for the reminder of his military service. In June 1929 he became a test pilot for Vickers Ltd. (Aviation Department). He became the company’s chief test pilot in 1932.
During his career as a test pilot, “Mutt” Summers made the first flights of 54 prototype aircraft, including the Spitfire, the Vickers Type 618 Nene-Viking, the Vickers Type 630 Viscount four-engine turboprop airliner, and the Vickers Type 667 Valiant, a four-engine jet bomber. He flew more than 5,600 hours in 366 different aircraft types.
“Mutt’s approach to test flying was much more in sympathy with the knee-pad than with the complicated automatic observers which nowadays are an indispensable part of test flying. He vigorously defended the feel of an aeroplane as measured by his hand or by the seat of his pants, and I believe was always suspicious of the scientific approach. . . One learned never to regard his criticism or advice lightly. In a world of science and instrumentation his judgement and horsesense often threw an unscientific but accurate light on some dark problem.” —Sir George R. F. Edwards, OM, CBE, FRS, DL, Executive Director of the British Aircraft Corporation, quoted in Flight and Aircraft Engineer, No. 2357, Vol. 65, Friday, 26 March 1954, at Page 355, Column 2.
Joseph Summers, Esq., was appointed an Officer of the Most Excellent Order of the British Empire, Civil Division (O.B.E.), in His Majesty’s New Year’s Honours, Wednesday, 9 January 1946. He was promoted to Commander of the Most Excellent Order of the British Empire (Civil Division) (C.B.E.) in Her Majesty’s Coronation Honours, Monday, 1 June 1953.
Summers died 16 March 1954 at the age of 50 years.
