that in 1961, the Valiant having seen its day, No. 18 Squadron was disbanded. The Vulcan OCU stayed with RAF Finningley from June 1961 until December 1969. In 1970 there was an arson attack on Number 2 Hangar by a serving RAF member. After the hangar was locked and secured at 1700hrs he lit a fire under an aircraft, obviously with catastrophic results. The hangar was badly damaged, and the perpetrator charged and imprisoned. Handley Page Victor bombers were added to the Finningley scene in later years before RAF Strike Command (the amalgamation of Bomber Command and Fighter Command on 30 April 1968) moved its units out and Training Command took over the station in May 1970. On 14 January 1992, a new Air Navigation School building was opened, built at a cost of £5.2m. Arguably the most famous of the Finningley's Avro Vulcan Bombers was aircraft XH558. On 1 July 1960 XH558 was the first Vulcan B.2 to enter RAF service and was immediately transferred to No. 230 Operational Conversion Unit at RAF Finningley before continuing its career. XH558 was restored to flight by the Vulcan to the Sky Trust and the aircraft was displayed during airshows until the end of 2015. On 29 March 2011 XH558 returned to Doncaster airport and Finningley, and she was once again at her original home. XH558 still resides there now, she remains in operating condition but without a permit to fly. Unfortunately, the three expert companies who were supporting the Vulcan in remaining airborne – BAE Systems, Marshall Aerospace and Defence Group and Rolls-Royce, collectively known as the ‘technical authorities’ - decided to cease their support at the end of the 2015 flying season. Without their support, under Civil Aviation Authority regulations, XH558 is prohibited from flying. Since moving to Doncaster, the Vulcan and Canberra WK163 have been removed from the hangar and have been left outside. Doncaster Council recently approved construction of a special built hangar for XH558 and WK163 but that will take years to construct. Units The following units were also here at some point: Facilities Aircrew training During the 1970s all RAF navigators passed through the Air Navigation School (ANS) of No. 6 Flying Training School (FTS) at RAF Finningley, when the BAe Dominie T.1 s of No. 1 ANS from RAF Stradishall and the Varsities of No. 2 ANS from RAF Gaydon moved there. In 1970, a
