The “Kestrel Evaluation Demonstration Team” was formed at RAF West Raynham in 1965 and comprised Sqn Ldr Fred Trowern, Flt Lt Tony 'Porky' Munro, Major Al Johnson, US Army, and First Lt Volke Suhr, WGAF. Demonstrations by the team were limited to invited guests and the media, and consisted of slow flight, hovering and vertical landings. On 15 October 1965 the team took part in a press photo-call at West Raynham, and on 25 November Fred Trowern carried out a single aircraft demonstration (high speed and VTOL) for a party of visiting VIPs.
