The beautiful hills of Northumberland hide the secrets of our almost forgotten recent history.The sites of many air crashes are difficult lt to locate, even though these aircraft and sometimes their crew met their fate relatively recently.Chris Davies has located and visited over 140 crash sites.In this thoroughly researched book, he discusses the location, history and stories surrounding thirty of these, from the German aircraft that crashed in the Cheviots during the Second World War to NATO exercises that went horribly wrong in the 1980s.Chris's work in discovering where these men lost their lives has provided closure for many families.Simon Colverson, the nephew of P/O M. W. Rivers, commented in a note of thanks, 'The sight of nearly forty people grouped together on a remote and windy hillside nearly seventy years after the crash to commemorate my uncle was deeply moving, and I will cherish the memory for the rest of my life.' Chris provides a major piece in the jigsaw of aviation history in Northumberland, recording an important part of Northumberland's local history that might otherwise have been lost in the mists of time.
