D-Day minus Three

2024 is the 80 anniversary of the D-Day landings at Normandy.

Radar, and technology used to jam it, played a decisive role in the landings.

Developed by Joan Curran, ‘chaff’, also known as ‘window’, was dropped by Avro Lancasters over the Straits of Dover to confuse German radar sets, creating a signal that was mistaken by German radar operators as an invasion fleet heading towards Calais. This helped to deceive Nazi High Command about the true location of the main landings.
