Like his skipper, Jack Powell, the navigator, came from Yorkshire; he was 31 at the time of his death, old for the wartime RAF and the oldest man in the crew.
Five foot nine inches, with brown hair, blue eyes, and a thoughtful, serious and determined face, Jack had spent most of his life in the large manufacturing town of Wakefield. He came from a very poor family but at some stage money became available which permitted him to escape the usual fate of gifted working class boys, for instead of having to leave school early he was able to continue his education.
He became a chartered accountant working in local government, was regarded as a high flyer, and would probably have ended up as a County Council Treasurer.
With his independence assured, he was able to go ahead and marry his long-time sweetheart Agnes. It was a match made against the wishes of his family, who despite their own poor origins now apparently considered that Agnes was beneath him.
Agnes, however, was extremely pretty, and a very positive, determined and strong-minded young woman who passionately wanted to better herself. They made a most handsome couple when they married on Christmas Eve 1937.
When the war began, Jack was in a reserved occupation, quite safe from danger, but after a long struggle with his conscience he told Agnes he was going to volunteer, he did not want other people to fight his battles on his behalf. Poor Agnes found it very hard to accept his decision.
Jack joined the RAF in 1941, and became a first-class navigator, with much of his training taking place overseas. Agnes moved back to her family in Wakefield, taking work in a munitions factory to help the war effort.
