Telegraph | News | Bletchley hums again to the Turing Bombe

The last time that the rattle of the Turing Bombe was heard, it was the greatest secret of the British Empire.

With a rumble that turned into a roar, a sound not heard at Bletchley Park for more than half a century, the machine that was at the heart of Britain's wartime code-breaking triumph began to work again.

Fantastic.
