I am constantly amazed by the information that emerges from this thread. Thanks to JW411 we now know that Alistair Panton was a Blenheim pilot who also spent most of the war in captivity after a remarkable if brief career. Yet like his fellow POW Rupert he also considered his flying career as a failure, as his granddaughter says in her excellent book
Six Weeks of Blenheim Summer:
... shot down a fourth time, captured and made a prisoner of war, Panton describes Six Weeks of Blenheim Summer as a story of failure. Whilst he survived, so many of his friends and comrades did not, and this grief never left him.
It's an excellent book and tribute to those who gave so much for their country, and will be enjoyed by anyone who follows this thread.
