Rudolf Hess
I went to a presentation at the Berkshire Museum of Aviation a couple of years or so ago and the guest speaker there gave a very interesting account of the life and death of Rudolf Hess. In summary, that there was an aircraft crash in north Scotland during WWII and on board was both the Duke of Kent and Rudolf Hess. Immediately after the crash there was a manifest souls count which quickly and directly reported back to Churchill. It indicated that there were no survivors.
Unknown at the time was that there was a survivor who was in the tail-gunner position who got free and climbed down the other side of the mountain the following day before blowing notifying the authorities. The man in Spandau prison was a substitute and his suspicious death pre-empted and prevented him spilling the beans before he would die of natural causes. Churchill slapped a 100-year curtailment on the release of all the files. I'm intrigued as one of our veteran group members was on duty as Spandau at the time of the "Hess" death. G.
