My Dad and the US Army Air Corps

I wish I knew the whole background of how Dad decided to leave his job at the shipyard to join the US Army Air Corps (predecessor to the US Air Force) as a flying Cadet. I suspect the lure of the air got to him or the idea of flying was more attractive to him than the thought of being drafted into the infantry. {This resurfaces later in my story with respect to the possibility of being drafted to go to Viet Nam.}.
