Will we ever know why Rudolf Hess flew to Scotland ?

On 10 May 1941, Rudolf Hess (26 April 1894 – 17 August 1987) made a solo flight to Scotland, where he hoped to arrange peace talks with the Duke of Hamilton, whom he believed to be a prominent opponent of the British government's war policy. The British authorities arrested Hess immediately on his arrival and held him in custody until the end of the war, when he was returned to Germany to stand trial at the Nuremberg trials of major war-criminals in 1946. During much of his trial, he claimed to be suffering from amnesia, but he later admitted this was a ruse. The Court convicted him of crimes against peace and of conspiracy with other German leaders to commit crimes. He served a life sentence in Spandau Prison; the Soviet Union blocked repeated attempts by family members and prominent politicians to win his early release. While still in custody as the only prisoner in Spandau, he hanged himself in 1987 at the age of 93. After his death, the prison was demolished to prevent it from becoming a neo-Nazi shrine.
