Query: Gives a more thorough account of the aviation pioneer

Unlike other aviation pioneers Wiley Post could not seem to translate his record-making flights into financial security for himself and his family and so he always seemed to push himself further and further in order to accomplish something that would place himself in a position where he could write his own ticket. This push nearly ended his life more than once and certainly contributed to the tragic accident in Alaska which ended his story.The authors did a wonderful job on this book, researching Wiley's background and putting everything in perspective for the reader. The deliberate sabotage attempts on several of Wiley Posts flights is something I was not aware of and which I felt could have been pursued more.Certainly a book for those who want to know more about this early flier and American hero.
