Deep in the beautiful Worcestershire countryside lie a number of secret places that played a special part in protecting a generation from the onslaught of a world war. Travellers passing through leafy Worcestershire lanes may catch a glimpse of a structure that seems out of place against the backdrop of fields and hills – the dish of a gigantic radio telescope. How did such an incongruous structure arrive in the middle of nowhere, and what does it do? This book answers the question, and recounts the dramatic history of two 'Top Secret' wartime airfields, and how their activities were inextricably linked to the 'boffins' of the Malvern Telecommunications Research Establishment. It tells the story of brilliant inventions, wartime courage and sacrifice, tragic air crashes, and ordinary and extraordinary people, pushing themselves and their machines to the limit and beyond. Crafted using personal recollections – the book reveals the truly extraordinary wartime commitment and camaraderie that fuelled extraordinary endeavour and achievement.
