I see that Neville Chamberlaine's ticket to Munich has been found.
A faded ticket, dated September 29 1938, has been discovered among the possessions of the late George William Denny, one of the founders of British Airways, and reveals that Chamberlain flew to Munich at 8.30am on ticket number British Airways 18249.
Apart from the obvious question of whether there was a British Airways in 1938, one can only hope that this isn't a hoax on the scale of the Hitler diaries, Binyamin Wilkomirski's Fragments or the infamous posthumous Hitlerian bank account where income from Mein Kampf was supposed to go.
