I watched a film last night called 'The Arrow' - what an amazing story. In 1941-2 Avro produced the Lancaster bomber - the mainstay of RAF Bomber Command during the second half of WWII. Just 8 years after the war ended in 1945, Avro changed from such classic propellor-driven aircraft to a delta-wing jet capable of Mach 2 and which would be competitive with all but one or two fighter aircraft today, some 60 years later. At the time the aircraft flew (1957-9), there was nothing in the world to compare it with. A truly extraordinary feat of engineering, which was defeated not by technical limitations, but by political decision-making.
