On 10 May 1941, on a whim, Hitler's deputy Rudolf Hess flew a Messerschmitt Bf 110 to Scotland in a bizarre effort to make peace with Britain; Göring sent fighters to stop him but he was long gone. Imprisoned and tried at Nuremberg, he would die by his own hand in 1987, aged 93. That's the accepted explanation. Ever since, conspiracy theories have swirled around the famous mission. How strong were Hess's connections with the British establishment? Was the death of the king's brother, associated with the Hess overture for peace? Often overlooked, until now, here Harris and Wilbourn provide an analysis of the flight itself - the flight plan, equipment, data sheets, navigation system - and come to a startling conclusion. Using original photography, documentation and diagrams, Rudolf Hess sheds new light on one of the most intriguing stories of the Second World War.
