Aviation - Bletchley Park - 2008.

The Bletchley Park trip took place on the 2nd May 2008. A fascinating day.

During the war Bletchley Park was devoted to cracking enemy codes, in particular those produced by the Enigma Machine

Work was carried out in several wooden huts; Hut 6 housed the group working on breaking the German army Enigma code.   The naval code was tackled in hut 8 and was initially broken by June 1941, this brought about a dramatic reduction in the loss of allied shipping in the Atlantic

More sophisticated ciphers were used during later stages of the war and the Colossus computer, containing 2,400 valves and weighing a ton, was completed in 1944.   This machine was the first computer and succeeded in breaking the Lorenz code used by Hitler and his generals.   This was designed and built by the late Tommy Flowers of the British Post Office.

Exploring Bletchley Park is tiring but, at the end of the day, we had the opportunity to relax.
