I believe he is referring to the fix as an analogy in reference to departing the initial approach fix or final approach fix. You call it in an instrument approach procedure as a reference point to where in the sky you are located. Of course i could be wrong because we are talking 37 years experience to 2 but that is what i took it as. The fix being just a point in his life that he passed, a checkpoint if you will.
I am not very philosophical though so dont critique me too bad 2dots.
Real nice explanation, usmc. Your philosophical metaphor was just fine. Stay safe over there, and have a blast when you come home. Gluck in your flying endeavors, as well.
