BBB2 to reshow #Turing #Bletchley Park documentary

This Sunday (Oct 28 8:00pm) BBC2 is giving us another chance to see its excellent Timewatch programme  "Codebreakers: Bletchley Park's Lost Heroes", giving overdue recognition to the brilliance of Bill Tutte and Tommy Flowers. The BBC says the documentary "reveals the secret story behind one of the greatest intellectual feats of World War II, a feat that gave birth to the digital age. In 1943, a 24-year-old maths student and a GPO engineer combined to hack into Hitler's personal super-code machine - not Enigma but an even tougher system, which he called his 'secrets writer'." 
   If you thought that Bletchley Park was just about Alan Turing, Enigma and U Boats you're in for a pleasant surprise!
