To Shatter the Sky, subtitled Bomber Airfield at War, is a book and also a BBC television programme of the same name by the military historian, author and screenwriter Bruce Barrymore Halpenny. The author was already working on the book when he was approached by the BBC to produce a related theme for a history programme, hence the book and programme sharing the same name. The programme was aired on BBC1 in late 1983 and the book launched in early 1984. Source: Wikipedia (en)
