the meeting, Hamilton examined the remains of the Messerschmitt in the company of an intelligence officer, then returned to Turnhouse, where he made arrangements through the Foreign Office to meet Churchill, who was at Ditchley for the weekend. They had some preliminary talks that night, and Hamilton accompanied Churchill back to London the next day, where they both met with members of the War Cabinet. Churchill sent Hamilton with foreign affairs expert Ivone Kirkpatrick, who had met Hess previously, to positively identify the prisoner, who had been moved to Buchanan Castle overnight. Hess, who had prepared extensive notes to use during this meeting, spoke to them at length about Hitler's expansionary plans and the need for Britain to let the Nazis have free rein in Europe, in exchange for Britain being allowed to keep its overseas possessions. Kirkpatrick held two more meetings with Hess over the course of the next few days, while Hamilton returned to his duties. In addition to being disappointed at the apparent failure of his mission, Hess began claiming that his medical treatment was inadequate and that there was a plot afoot to poison him. Hess's flight, but not his destination or fate, was first announced by Munich Radio in Germany on the evening of 12 May. On 13 May, Hitler sent Foreign Minister Joachim von Ribbentrop to give the news in person to Mussolini, and the British press was permitted to release full information about events that same day. On 14 May, Ilse Hess finally learned that her husband had survived the trip when news of his fate was broadcast on German radio. Two sections of the fuselage of the aircraft were initially hidden by David McLean and later retrieved. One part was sold to the former assistant secretary of the Battle of Britain Association, who gave it to a war museum in the US; this part was later sold by Bonhams at auction. Part of the fuel tank and a strut were offered for sale via Bonhams in 2014. Other wreckage was salvaged by 63 Maintenance Unit between 11 and 16 May 1941 and then taken to Oxford to be stored. The aeroplane had been armed with four machine guns in the nose, but carried no ammunition. One of the engines is on display at the RAF Museum while the Imperial War Museum displays another engine and part of the fuselage. Trial and imprisonment
