Castles In The Sky Blu-Ray

This is the remarkable human drama behind the invention that was to prove pivotal in the Battle of Britain. Eddie Izzard stars in this funny, moving and inspiring factual drama about the pioneering work on radar by a little know team of scientists in the run up to the Second World War. On 26th February 1935, Robert Watson-Watt demonstrated for the first time that aircraft could be detectd by bouncing radio waves off them. By the time the war began in 1939, radar stations were dotted along the British coast, tracking aircraft at distances of 100 miles away. It was this invention - more than any other - that saved the RAF in the 1940 Battle of Britain. But getting to this stage was a battle in itself.
