Bristol Type 188 (XF926) Snapped at Cosford Airshow 19 June 2016.
The Bristol 188 was a British supersonic research aircraft built by the Bristol Aeroplane Company in the 1950s. Its length, slender cross-section and intended purpose led to its being nicknamed the "Flaming Pencil". The advanced nature of the aircraft meant that new construction methods had to be developed. Several materials were considered for construction and two specialist grades of steel were selected: a titanium-stabilized 18-8 austenitic steel and a 12%-Cr steel used in gas turbines (Firth-Vickers Rex 448). These had to be manufactured to better tolerances in sufficient quantities for construction to start. The 12% chromium stainless steel with a honeycomb centre was used for the construction of the outer skin, to which no paint was applied. Riveting was a potential method for construction but the new arc welding technique using an Argon gas shield known as puddle welding was used. There were long delays with the method, which was less than satisfactory. The W. G. Armstrong Whitworth company provided substantial technical help and support to Bristol during this period; they produced major sections of the airframe as a subcontractor. (From Wikipedia)
