Did you ever read, "Everything But The Flack?" I have a tattered, dogeared copy in paperback, yellowed and held together by a rubber band. I believe it was written by Martin Caidin, and tells the story of the trials and tribulations of rehabilitating the B-17's they needed to film the movie, "The War Lover."
I tried to find it! It's out of print ... so too is "God Is My Copilot" ... I enjoyed "Always" since it was a remake of "A Guy Named Mike" .... starring Spencer Tracy .... a WWII movie ....
