I recently learned of how my grandfathers lack of seniority may have preserved our family. He was in the Navy reserves and active duty from early1930’s to 1972. In 1940 he was a reserve CPO and was activated. Another CPO had a few months seniority on him and duty stations picks were Pearl Harbor and a yet to be built NAS in Chamblee Ga. Other guy was single and Gpa had wife and 2 kids. Other Chief picked Pearl. The decision was fateful in several ways. Sadly in 41 the other Chief died in the Dec attack on Pearl. For Gpa , he was commissioned a Lt. and because he had a civilian pilots license sent to flight school to train new Navy pilots in Chamblee. Never saw battle situations as he was 10+ years older than new pilots. After the war his training services were not needed. He could stay in reserves as an officer but tied to a desk or be demoted to Chief and still be involved with flying. He picked Chief. Didn’t last long tho, He was reactivated before Korea back to Lt. and spent the rest of his Navy career as a flight instructor and admirals jockey. Retired a a Lt. Commander. He said that if he was 10 years younger in 1941 he would have been involved in battle situations and probably would have advanced in rank more than he did. Family was happy that he didn’t I’m sure. Duty stations in California,Memphis, Joliet,Corpus Christi, NJ. Newfoundland, Virginia,Puerto Rico, Albuquerque. Mom and Gpa had always told me stories about his service but not the fateful duty station pick version.
