That would be Colonel, and it would be navigatOrs not navigatErs.
Your rank may have been Colonel. I would have Saluted you and argued with you. I did with a some of officers that I flew with and they knew that with my tool box, that their engines would keep turning and burning and they would stay airborne. Remember this Colonel, WE are BOTH AIRMEN and we always have been. I send you the salute and also the arguing. Thank you sir for the spelling lesson.
