Before Wally Layne of the Fletcher crew became a Pathfinder, he served on 50 Squadron. His CO was the legendary Gus Walker, who would lose part of his arm in a bomb explosion whilst trying to ensure that nobody would be hurt.
When Walker left 50 Squadron for 106 Squadron, he sent the NCOs of 50 Squadron a Christmas Card. For the story of Gus Walker’s accident and the Christmas card, see our new page: Gus Walker, Wally Layne, and Christmas
