The Sedbergh TX Mk.1 is more affectionally known as “The Barge” (many civilian versions had individual names such as “Daisy”, “Buttercup” or even “Lady Godiva”). The T21B (its civilian designation) must rank as one of the best and most loved of Slingsby’s gliders. This two seat, side by side trainer is robust and delightful to fly. For instructors it was a stable training machine as well as an excellent soaring aircraft and it led the move from solo to dual training in civilian clubs.
First produced by Slingsby in the 1944 (without Air Ministry approval) the T21B version went into production in 1947. Popular with both civilian clubs and the Air Cadets the Sedbergh was produced in large numbers with a total production of around 220 gliders. The RAF Air Cadets received over 90 Sedberghs, with yet more going to the RAFGSA and the type remained in use until the mid-1980’s. Its side-by-side seating and good soaring ability makes it a popular glider with vintage enthusiasts today.
WB922 was delivered to the RAF College Cranwell 13th June 1949. Spending time at various locations in particular 662 VGS (Arbroath), 663 VGS (Aberdeen Airport) between 1965 and 1976 and “Centre” at Syerston (1981). Whilst in Scotland WB922 was used for the training and first solo of Prince Andrew whilst at Gordonstoun and has since become known as the “Royal Barge”. Ending its service days with 615 VGS (Kenley) WB922 passed through a number of civilian hands before joining 621 VGS Historic Flight in February 2004.
