In WW2 my dad was a flight engineer in 582 squadron, flying Lancasters. In his lifetime he rarely wanted to talk about those days.
Last night I went to a talk on the Pathfinders. My dad was incredibly brave and one of my greatest regrets was not telling him so. He was lucky to survive the war. I can only imagine the sheer terror of getting into those cold, cramped planes in the dead of night knowing that he risked being killed over enemy territory on every raid.
