I heard a story (I think on Paul Harvey, may he r.i.p., too) that Art had been in a very bad car accident before WWII and that both his legs were shattered. At that time he was a pilot. He was told that he would never walk nor fly again; however, the Paul went on to tell that not only did he walk, but he also flew planes during WWII. Don’t know what his missions were, but “now you know the rest of the story.”
Nice story, but there’s nothing in his bio to indicate any aspect of this.
