I can recall and poin to any number of those moments in my earler days. I never forgot what my navigator flight instructor once told me.... "All navigators will make mistakes. The difference between the better navigators and those not so successful is in quickly recognizing the mistake and how quickly it can be corrected." That philosophy has stayed with me and worked well for me ever since.IMany times after completing a backcountry trip i would recall mistakes I made and learning fom them I resolved to never do that again. But I felt I learned much more after those trips than on trips where everything went perfectly well. Thankfully with time and age, I think, I have learned to avoid most of the bad stuff now.
We had lots of USAF Navigators living in our neighborhood back when Pease AFB was still operational full time. Their fellow pilots (there were many) affectionately referred to them as "naviguessers".
