A distant cousin, who passed on many years ago, flew with those missions at the end of WWII and the Berlin Airlift, and went on to fly with early Air Force One crews. He told stories about those days, but never told exactly what role he had. It wasn't allowed back then. But when he would come home, we had "overflow" family (the evicted kids, to make room) sleeping in the guest rooms.
I wish my memory of that time was better, but age catches up with us all.
