Query: Very special book.

Many many years ago, I was a young man intent on being the next Naval Aviator jet pilot, when my eyesight failed me and my path became the Naval Flight Officer: an officer who navigates and operates weapon systems and communication systems on the Naval aircraft.In my anger and frustration in being denied the dream job of my life, I picked this book up and read it: Guy Merchie's descriptions of the life of a Navigator gave me hope. This book showed me just how amazing it was going to be to simply be able to fly at all.This book helped an angry young man realize how grateful he should be to learn the ways of the Navigator; the man who threads the needle of the sky.Great book for anyone who loves aviation; for anyone who gets chills when they read John Gillespie Magee's "High Flight".
