Royal Aeronautical Society Podcast

Helicopter man Roger Cansdale CEng FRAeS reflects on a remarkable four-decade career in aerospace and weapons development with the Royal Aircraft Establishment (RAE) and QinetiQ. From helicopter programmes and advancing flight safety to contributing to cutting-edge weapons systems, Roger shares his insights on the innovations, challenges, and his lasting impact on UK aviation and defence.
After graduating from the University of Bristol in 1964, Roger began his distinguished career at Farnborough, first with the RAE and later as part of QinetiQ. He started in the Structures Department’s Dynamics Division before moving, ten years later, to the Airworthiness Division, where he played a leading role in ensuring the structural integrity and flight safety of UK military helicopters.
Roger’s helicopter work included providing expert guidance on the Westland Lynx and first-hand involvement in developing the BERP rotor (British Experimental Rotor Programme). He describes problem-solving as one of the most satisfying aspects of his career and highlights the strong partnerships he built with Westland. He also involved in assessing the safety of historic Army helicopters, where his careful judgement contributed to the Civil Aviation Authority’s decision to withdraw the Skeeter’s permit to fly.
Later in his career, after a brief period in the RAE’s Management Support Unit, Roger broadened his expertise to weapons systems, including work on the Matra-BAE Storm Shadow programme.
Looking back, Roger fondly recalls a memorable anecdote from his student years: a summer spent in the United States working with actor Buster Crabbe, famous for his roles as Flash Gordon, Buck Rogers, and Tarzan.
Roger’s achievements have been recognised with numerous awards. He received the N E Rowe Medal from the Royal Aeronautical Society (RAeS) for a paper written while at university. Later, he was honoured with the RAeS Bronze Medal for outstanding contributions to flight safety, following a nomination by Westland, and the prestigious Wakefield Gold Medal.

In the latest podcast in the series from the Royal Aeronautical Society's monthly AEROSPACE magazine, Editor in Chief Tim Robinson, Deputy Editor Stephen Bridgewater and Features Editor Dominic Ward analyse recent aviation, aerospace and space news - and preview the newest (February 2026) edition of the magazine.

Why do companies choose to run apprenticeship programmes? We spoke directly to the employers who hire apprentices to explore the real value apprenticeships bring to their businesses, featuring insights from 2Excel Aviation and Marshall ADG.

As next week's biennial Singapore Airshow sets to ready to take-off next week, TIM ROBINSON FRAeS and STEPHEN BRIDGEWATER FRAeS preview the 10th edition of Asia's largest aerospace exhibition at the Changi Exhibition Centre from 3–8 February 2026.

Arthur’s highly successful career followed an unconventional path. He left school with a mix of GCEs, O Levels, and two A Levels, neither of which were Maths, but with plenty of practical know-how from his father. Describing himself as ‘vastly overconfident but vastly underqualified’, Arthur was unsure of his future until a careers adviser’s suggestion led him to Royal Aircraft Establishment (RAE) Farnborough.

In 1975, Arthur joined the Engineering Physics (EP) Department as an Assistant Scientific Officer, doing experimental research into helicopter transmissions. When the department closed in the early 1980s, he moved , now a Scientific Officer, to the Flight Systems Department, completing EP projects before working on aircraft hydraulic systems. This involved real aircraft which had to be cleared for flight, but ended after a Hunter aircraft suffered an engine failure on take-off. Both pilots ejected safely, but the project was transferred to RAE Bedford  leaving Arthur once again in search of a new post.

He described himself as being ‘hawked around’ the Weapons Department before settling in Attack Weapons, where he worked on anti-tank systems and again flight clearance on real aircraft. His practical approach earned promotion to Principal Scientific Officer and involvement in international missile programmes. Though he credited luck, his skills were clearly valued. Arthur saw the RAE as more a family than a workplace, and joining the Royal Aeronautical Society (RAeS) put him on the path to Chartered Engineer despite the lack of a degree.

The CEng grew in importance as Farnborough became DRA, DERA, and finally QinetiQ, a period Arthur called a ‘Wild West’ of unclear strategy and scarce funds. After a disruptive split of staff between QinetiQ and DSTL, he chose QinetiQ, but the ensuing chaos left him feeling ‘crushed.’ He eventually moved to Aldermaston, where his weapons and aircraft clearance experience was valued.

He then spent five satisfying years in work he found genuinely useful, a period of redemption that let him retire without the frustration of leaving Farnborough.

Arthur’s interests included long-term involvement with the Air Cadets and research into Operation Chastise. What began as a paper supporting his RAeS application and pursuit of Chartered Engineer status eventually led to him serving as a technical advisor for a TV programme on the Dambusters.

Reflecting on his career, Arthur felt a university degree at 18 wouldn’t have suited him. The informal apprenticeship at the RAE, guided by colleagues who recognized his potential, worked far better for his development.

When asked about the biggest change he witnessed over his career, Arthur highlighted the shift in organisational culture. At the RAE, trials could fail without fuss, provided no one was harmed; by QinetiQ, the same incident would prompt a full inquiry. The RAE’s “suck-it-and-see” approach fostered risk-taking, allowing Technical Demonstrator Programmes to succeed through building and tinkering, often before fully understanding the systems.

Arthur has written an account of the various phases of his career but has still to finish the “messy” bit.  He also enjoys writing aeronautical histories. His paper on the role of the RAE and the V1 was published in the RAeS’s Journal of Aeronautical History.
