No fond memories
I was stationed at McCook at the end of World War II.
I had been flying a B-24 in Europe until the end of the war there. We returned to McCook and were transferred into the B-29. We took this to mean we were scheduled to go to the Pacific theater.
We used the Norden in both planes, but the armed guard was usually the bombadier who had to sign the sight out for each mission. They carried a .45, usually in a shoulder holster. Actually most of the officers did carry the .45 but none of us could probably have hit a barn if we were inside of it.
Sorry, but I don't have particularly good feelings for McCook. This was after several years of the war and soldiers weren't too welcome anymore.
I did mention your town in my book, Clouds Are Always White On Top, but not in a very complimentary fashion.
