World War II was won with technology and no technology was more important than radar. Here, for the first time, is the complete drama of the secret race to develop radar, told in the words of one of the key participants. Nissen discovered a way to use radar to guide fighter pilots directly, rather than just to detect enemy aircraft. This 'secret' brought him both recognition and danger. In 1942 he volunteered for a dangerous commando mission to learn how to jam German radar. Because of his invaluable knowledge, he was assigned a bodyguard – South Saskatchewan Rifles – who had orders to kill him if he fell into enemy hands. Nissen and one Canadian were the only survivors of the special group. What he learned during that mission went a long way towards making D-Day and eventual liberation in Europe possible. Here is the suspense-filled story of the experiments, the inventive breakthroughs, the electronic eavesdropping, and the sheer good luck that helped the Allies win the Radar War.
