least two operational Gloster Meteor jet fighters, a squadron of twin tail-boomed de Havilland Venoms and de Havilland Vampire trainer jets. The very latest arrival in 1957 was a flight of Gloster Javelins, which also appeared at the Farnborough Airshow the same year. The 1956 Hawker Hunter multiple aircraft accident happened on the morning of Wednesday 8 February 1956. Eight Hawker Hunter aircraft from the Central Fighter Establishment took off on an exercise. The weather closed in, causing them to be diverted to RAF Marham. Two aircraft landed safely, a third ran off the runway, and the fourth crashed into a field killing the pilot. The remaining four pilots ejected, with the aircraft crashing in open country. This incident was raised in the House of Commons. In 1964 a tripartite squadron, comprising members of the British, American and German armed forces, was formed at West Raynham to evaluate the Hawker P.1127 Vertical Take-Off and Landing (VTOL) strike fighter aircraft. In 1964, the East side of the airfield was developed as a SAM site, equipped with the Bristol Bloodhound Mk2 and its associated radars. The resident unit was No. 41 Squadron RAF. Some of the radars, launch control units, and launchers were air portable for deployment elsewhere if required. Between 28 and 31 March 1967 Hawker Hunters from West Raynham were involved in Operation Mop Up. This operation saw repeated attacks by Hunters from Raynham and RAF Chivenor, along with aircraft of the Fleet Air Arm, dropping aviation fuel and napalm on an oil slick being released from the wreck of the supertanker which had run aground on Seven Stones reef, near Lands End. On 9 June 1967 a Handley Page Hastings C2, registration WD491, was written off at Raynham when a tyre burst during landing. In 1968 a Hunter from RAF West Raynham was used by Flight Lieutenant Alan Pollock, a flight commander in No. 1 Squadron RAF, to unofficially mark the 50th Anniversary of the Royal Air Force. This event is commonly referred to as the Hawker Hunter Tower Bridge incident. On 19 December 1975, 85 Squadron, which had been stationed at the base flying the Gloster Javelin and Gloster Meteor in the early 1960s, made their headquarters at West Raynham after being reformed as a Bristol Bloodhound Mark II surface-to-air missile unit. 85 Squadron remained at West Raynham until it was disbanded on 10 July 1991, with the
