Sibley and Roberts bring a vast wealth of experience to Project Fresson and the development of a commercially viable, zero-emissions, passenger-carrying service.

Cranfield Aerospace Solutions (CAeS) – the UK SME leading the Project Fresson consortium – is excited to announce two important new advisory roles with over 80 years combined engineering experience.

Cranfield Aerospace Solutions welcome Nick Sibley (left) & John Roberts (right)

Nick Sibley graduated from Bristol University in Aeronautical Engineering in 1978 and started his career as an aerodynamicist on the Sheriff light twin.  He later became Chief Engineer on the ARV 1 two seat light aircraft built on the Isle of Wight. In 1989 he joined British Aerospace as Chief Designer on the Jetstream 41 project.  When the J 41 entered service he moved across to the ATP as Chief Designer and ultimately, Engineering Director for all BAE Systems Civil Aircraft. During his BAE Systems career he consulted on a number of military aircraft programmes plus land vehicles covering both design and support solutions.  His final years in BAE Systems was in the maritime side of the business covering ships, radars, torpedoes and naval bases.  Since leaving BAE Systems he has consulted on a range of legacy and technology projects.

John Roberts graduated from Brunel University, London, also in 1978 with a degree in Mechanical Engineering and joined Dowty Fuel Systems working on control equipment for jet engines. In 1992 he joined British Aerospace Airbus as Chief Systems Engineer. Five years later he became the UK Chief Engineer for the A330/340 programme. After a period at Messier-Dowty as Vice President of Engineering, he rejoined Airbus as the UK Chief Engineer for the A380, a position held through the challenging period of the aircraft’s early in-service life.

As CAeS’s Project Fresson continues to make progress towards an emissions-free (zero CO2), hydrogen-fuel-cell-powered flying demonstrator by September 2022 the team will continue to expand. To learn more and apply to open positions please visit: or join us on Twitter @projectfresson.
