Wing Commander Kenneth Horatio Wallis MBE CEng FRAeS RAF (26 April 1916 – 1 September 2013)[1] was a British aviator, engineer, and inventor. During the Second World War, Wallis served in the Royal Air Force and flew 28 bomber missions over Germany; after the war, he moved on to research and development, before retiring in 1964. He later became one of the leading exponents of autogyros and earned 34 world records, still holding eight of them at the time of his death in 2013.[2]

Key Information

Early life

[edit]

Born on 26 April 1916 at Ely, he was educated at The Kings' School Ely Cambridgeshire. Wallis developed a practical interest in mechanics, building a motorcycle at the age of 11. In 1936, he was inspired by a demonstration by Henri Mignet of his Mignet HM.14 Pou-du-Ciel ("Flying Flea"). Using only Mignet's book, Wallis gathered the materials required, and started to build his own Flying Flea. He abandoned construction because of widespread adverse publicity about fatal accidents that implied inadequate design of the type.[3]

Wallis took an interest in powerboats which he kept up until 1957, when he won the 56-mile (90 km) long Missouri Marathon.

Military career

[edit]

Wallis applied for the RAF's Volunteer Reserve Service but was turned away because of an issue with his right eye. Consequently, he obtained a private flying licence, which required only a certificate signed by his GP. In 1938, Wallis again tried to join the RAF, but failed the eye test. He applied again in 1939 and finally passed the eye test, explaining, "I did the first line with my good eye then they covered it up and asked me to read the bottom line with my bad eye, without them realising I just turned my head slightly so I could again see with my good eye—I passed it with Above Average Eye Sight!"[4]

Wallis was commissioned in the Royal Air Force Volunteer Reserve on 28 December 1940 as a pilot officer (on probation), with seniority in that rank from 1 December 1940.[5] His commission was confirmed on 28 December 1941 and he was promoted to flying officer (war substantive) with seniority from 1 December 1941.[6] He was promoted to flight lieutenant (war substantive) on 28 December 1942, with seniority from 1 December 1942.[7]

Wallis's military career started with Westland Lysander patrols in the RAF. In 1942, he was transferred to RAF Bomber Command, flying Wellingtons near Grimsby. Wallis subsequently served in Italy and on secondment to the United States Strategic Air Command, where he flew the massive Convair B-36, which had six piston engines and four auxiliary jet engines.

Following the end of the Second World War, he was involved in research and development, and was awarded a number of patents on his inventions. On 1 May 1947, he service in the RAF was extended by four years and he transferred to the Technical Branch, with seniority in the rank of flight lieutenant from 1 September 1945.[8] He was given a permanent commission on 22 June 1948, allowing him to serve until retirement.[9] He was promoted to squadron leader on 1 January 1953,[10] and to wing commander on 1 July 1958.[11] He left the RAF in 1964, retiring to Norfolk.

Autogyros

[edit]

Wallis who lived at Reymerston Hall, Norfolk produced autogyros for, in his own words, "reconnaissance, research and development, surveillance and military purposes", and his designs were not available for enthusiasts as he considered that although the design is simple, it has to be built to the appropriate standards. His contribution to autogyro design included the "offset gimbal rotor head".[12]

Wallis had the help of Beagle Aircraft in building five Wallis WA-116 autogyros at Shoreham in 1962 for evaluation by the British Army. This collaboration ended when the British Army chose the Westland Sioux for this role.

Wallis worked as Sean Connery's stunt pilot in the 1967 James Bond film You Only Live Twice, where he flew one of his WA-116s named Little Nellie.

In 1970 it was announced that Airmark would produce his autogyro design with a certificate of airworthiness, that being essential for commercial use of the autogyro. Expected price was around £3,000.[13]

Between 2006 and 2009, Wallis took part in filming for Into the Wind, a documentary by Steven Hatton featuring the experiences and memories of wartime members of Bomber Command. The film, released in 2012, features Wallis demonstrating several of his autogyro designs.

Wallis was the President of the Norfolk and Suffolk Aviation Museum, and Patron of the Wolf Preservation Foundation.

Recognition

[edit]

Wallis was the recognized world record holder for many categories of autogyro records over the years, and was also recognized as the oldest pilot to set a world flight record at the age of 89. Wallis held most of the autogyro world records during his autogyro flying career. These include the Fédération Aéronautique Internationale time-to-climb,[14] a speed record of 189 km/h (111.7 mph),[15] and the straight-line distance record of 869.23 km (540.11 mi). On 16 November 2002, Wallis increased the speed record to 207.7 km/h (129.1 mph).[16]

Wallis appeared as himself on an episode of Tell The Truth dated 9 November 1984, discussing his autogyro record.

In the 1996 New Year Honours, Wallis received was appointed Member of the Order of the British Empire (MBE) "for services to autogyro development".[17]

In July 2013, Wallis received the Bomber Command clasp to his 1939 to 1945 Star for his 28 bomber missions over Germany during World War II.[18]

Later life

[edit]

He was married to Peggy Stapley, a Women's Auxiliary Air Force veteran, from 1942 to her death in 2003.[2][19] Wallis died on 1 September 2013, aged 97. Prior to his death, he was living in the Norfolk village of Reymerston.

Old Buckenham Airport held a memorial event on 29 September 2013 at the request of the Wallis family: "A Celebration of the Life of Wing Commander Ken Wallis".[20] It had been expected that about 500 people would attend, but an estimated 3,000 to 4,000 attended the event.[21][22][23]

He also innovated in other fields, such as building the world's first electric slot-car track in 1942 and developing specialized cameras. Wallis continued public demonstrations and performances into his later years, passing away in East Dereham, , at age 97.

Early Life

Childhood and Family Background

Kenneth Horatio Wallis was born on 26 April 1916 in , , during the height of . His family had deep roots in the region, with his father, Horace Wallis, operating a cycle and shop in Ely that served as a hub for local mechanical pursuits. Horace, born in 1883, was himself an enthusiast of early and , having co-built the "Wallbro" in 1910 and competed successfully in races, which likely instilled in young Ken a foundational appreciation for engineering and speed. Growing up in rural , Wallis experienced a childhood immersed in hands-on mechanics, influenced by his father's business where he began assisting at a young age. At just 11 years old, in , he undertook his first major project by building his own from scrap parts, demonstrating an innate mechanical aptitude that would define his later innovations. This rural environment, characterized by open fenlands and agricultural communities, provided ample space for such tinkering, though formal opportunities for technical education were limited by the era's constraints. The in Britain, marked by economic instability following and the of the 1930s, shaped Wallis's formative years in a working-to-middle-class household reliant on small-scale enterprises like his father's shop. Access to hobbies such as mechanics was often self-funded and improvised in rural areas like , where industrial resources were scarce, fostering resourcefulness amid broader socio-economic challenges that restricted many young people's aspirations beyond local trades.

Initial Interests in Engineering and Aviation

During the 1930s, Ken Wallis developed a strong interest in mechanics through self-directed learning and hands-on projects, drawing inspiration from his family's involvement in motorcycles and early experiments. Growing up in , where his father operated a cycle and shop, Wallis began tinkering at a young age; by 11, he had constructed his own from scavenged parts, honing skills that would define his approach. His extended to restoring and selling cars for profit, which funded his burgeoning passion for flight, while exposure to air displays and family stories of building the Wallbro Monoplane in 1910 further fueled his enthusiasm for . Wallis's first serious aviation endeavor came in 1936, when, at age 20, he attempted to build a Pou-du-Ciel "Flying Flea" aircraft after witnessing a demonstration by designer Mignet and studying Mignet's instructional book. Lacking formal training, he sourced materials and progressed on the project as a self-taught effort, but abandoned it upon learning of multiple fatal crashes linked to the design's instability, which led to a ban on the aircraft that year. Undeterred, he earned a private pilot's license that same year after just 12 hours of lessons in a Gypsy Moth, demonstrating his quick aptitude despite financial constraints. A significant barrier to professional aviation was Wallis's congenital vision defect, which limited sight in his right eye and required an eye patch during childhood; this condition caused his rejection from the Royal Air Force in 1936. In 1939, as war loomed, he reattempted enlistment and passed the eye test by memorizing the chart letters using his stronger left eye, securing entry into the RAF and transitioning from amateur pursuits to a military career. Wallis's mechanical versatility extended beyond aviation into other domains, exemplified by his success in powerboat racing, where he designed and competed in custom vessels built from surplus materials.

Military Career

World War II Service

Wallis joined the Royal Air Force in 1939 by deceiving the medical examiner about his longstanding vision defect in his right eye, which had previously led to rejections in the 1930s. He began his service with No. 268 Squadron, flying Westland Lysander aircraft on army cooperation patrols, a role that involved reconnaissance and liaison duties in support of ground forces. In 1941, Wallis transferred to RAF Bomber Command, joining No. 103 Squadron at RAF Elsham Wolds, where he initially served as second pilot before taking command of missions. He flew 28 operational bombing missions over Europe, primarily in Vickers Wellington bombers, targeting industrial and port facilities in cities such as Bremen, Cologne, Hamburg, and Essen during night raids. Promoted to Flight Lieutenant in 1942, he navigated the intense demands of Bomber Command, including high casualty rates where many crews did not return from sorties. Wallis's missions highlighted the perilous nature of these operations, with challenges such as anti-aircraft fire, fighter intercepts, and mechanical failures; on one occasion in September 1941, he baled out of a after it ran low on fuel, and in October 1941, he crash-landed following damage from a cable. Crew dynamics were critical for survival, as seen in his early pairings with co-pilot Tommy Westlake, emphasizing the reliance on teamwork amid the stress of repeated night flights. Following a period as a bombing instructor at No. 21 Operational Training Unit, Wallis was posted to in 1943, where he flew additional operations with No. 37 Squadron, including missions in Consolidated Liberator bombers against Axis targets in the Mediterranean theater.

Post-War Roles and Retirement

Following his service in , where he completed 28 bomber missions over , Ken Wallis transitioned to research and development roles within the Royal Air Force, focusing on aircraft armament and experimental testing. In the late 1940s, he experimented with warheads designed to target engines of German jet-powered aircraft like the Arado 234, to assess potential improvements and adaptations for British use. By the early 1950s, as an armaments officer on a squadron at RAF Binbrook, Wallis modified bombing procedures for the jet bomber and conducted tests on various weaponry, such as 25-pound practice bombs and rifle sights. He later served as Command Weapons Officer in Fighter Command, contributing to broader advancements in aviation ordnance. Wallis's career progressed through key promotions and specialized postings. In 1953, he was promoted to and assigned to an role, which allowed him to requalify on jet aircraft, including the and . From 1956 to 1958, he was on exchange with the , flying nuclear-armed bombers and gaining experience in strategic . Promoted to in 1958, he returned to the and served as a at the Aeroplane and Armament Experimental Establishment (AAEE) at Boscombe Down, where he oversaw weapons testing for the supersonic fighter. In 1961, he took command of the Tactical Weapons Group at AAEE, directing experimental flight testing and development of tactical systems, including guided weapons. During his final years in service, Wallis began exploring personal aviation interests alongside his duties. In 1962, while still active in the RAF, he collaborated with Beagle Aircraft at Shoreham to construct initial prototypes of his design, including five WA-116 models for evaluation by the Air Corps. After 25 years of service, Wallis retired from the RAF in 1964 at age 47, citing limited advancement opportunities and the cancellation of promising projects like the TSR-2 and . This marked his shift toward full-time civilian pursuits in aviation innovation.

Autogyro Development

Early Experiments and Collaborations

Following his retirement from the Royal Air Force in 1964, Ken Wallis dedicated himself to developing autogyros, drawing on concepts from pre-war designs by that he had encountered during . Inspired by the Bensen B-7 Gyroglider, which he first saw during the 1950s, Wallis began experimenting with lightweight rotorcraft in his spare time while still in service, acquiring McCulloch engines for initial tests. By 1959, he achieved his first tethered flight with a prototype, marking the start of hands-on development focused on adapting rotor systems for powered flight. In the mid-1960s, Wallis partnered with his cousin Geoffrey to refine these concepts, founding Wallis Autogyros Limited in 1964 to oversee design and production. This collaboration built on Wallis's earlier solo efforts, emphasizing practical refinements to pre-war ideas for modern applications in and short-range operations. Their work bridged his military research and development experience, including a brief collaboration with Beagle Aircraft in 1962 to construct initial prototypes. Wallis's first powered autogyro flight occurred in 1961 with the prototype registered G-ARRT, prior to the formal WA-116 series, where he tested basic rotor and integration using a modified Bensen frame. These early tests highlighted challenges in achieving flight, particularly in preventing excessive rotor during maneuvers, which Wallis addressed through an offset rotor head for enhanced hands-off stability. He also overcame integration issues by optimizing the McCulloch powerplant for reliable application, enabling short capabilities under 25 meters while maintaining control in varying wind conditions. Wallis's World War II engineering experience, gained from RAF bomber operations and post-war radio direction-finding projects, profoundly influenced his approach to lightweight rotorcraft, distinguishing autogyros from fixed-wing aircraft by prioritizing autorotative lift over powered rotation for safer, more agile low-altitude performance. This background allowed him to apply principles of structural efficiency and vibration damping from wartime aviation to create compact, stable platforms suitable for civilian and military experimentation.

WA-116 Series and Key Designs

The WA-116 series represented Ken Wallis's primary innovation in single-seat design, evolving from his earlier experimental work and entering production through collaboration with Aircraft in the early 1960s. The series began with prototypes in 1961, but key builds, including those for military evaluation, were constructed starting in 1962, with five units built by , three of which were for the Air Corps. By 1966, Wallis had refined the design further, incorporating improvements in stability and control, such as an offset head that enabled hands-off flight. Variants within the series included the WA-116/F, optimized for high-speed performance with a modified powerplant, and the WA-116/T, a two-seat configuration initiated in 1969 after the completion of nine single-seaters. Central to the WA-116's design was its lightweight construction and portability, featuring a steel tube frame and wooden blades for durability and ease of maintenance. The was powered by a 72 hp (54 kW) McCulloch 4318A four-cylinder, air-cooled, horizontally opposed , providing reliable performance for short operations. The two-bladed system, with a of 6.20 meters, could be folded for transport, allowing the entire to fit into compact containers, which enhanced its utility for and expeditionary roles. These features emphasized Wallis's focus on agility and deployability over raw power. A standout example in the series was the WA-116/M, known as Little Nellie, specially constructed in 1966 for the film You Only Live Twice (1967). Built by Wallis himself, this variant was based on an existing WA-116 repurchased from the and modified extensively for cinematic sequences. Enhancements included the addition of prop weaponry such as machine guns, rocket launchers, air-to-air missiles, aerial mines, and a , all non-functional but designed to simulate intense aerial combat. The also received reinforced elements resembling armored plating to withstand the rigors of filming, including low-level maneuvers and mock battles, while retaining the folding for on-set portability. Wallis personally piloted Little Nellie for over 85 flights during production, logging more than 46 hours in and . Other notable designs in Wallis's lineage included the WA-116/F, which achieved prominence in speed-oriented applications, and the WA-118, a two-seater variant powered by a 100 hp Rolls-Royce Continental O-200 engine, intended for training and tandem operations. These evolutions built on the WA-116's foundational principles, prioritizing safety, simplicity, and versatility in autogyro flight.
