Castles in the SkyCastles in the Sky

A 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 26 February 1935, Robert Watson-Watt demonstrated for the first time that aircraft could be detected 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.
