In 1965 I volunteered for the Air Force. I signed up for 5 years so I could be a pilot. Jobs were scarce in SW PA where except in coal mines. My father had already did a stint of 30 years and was suffering fro black lung.
I did all the test, passed with flying colors and went for my physical. I passed everything and was walking down the hall to the last doctor. They pulled me out of the line and checked my back. I had limp they said I would never make it out of Basic Training. They put big a slash across my paper work and FAILED. 30 seconds changed my life, Navy, Army or Marines would not even consider me then. I would probably would not have survived Vietnam.
It was tough 2 years until I finally landed a job with Sandia Laboratory in NM . First thing , I was put in a group designing weapons used in Vietnam.
Always felt guilty for not being able to go, but I truly thank all those that served and especially for those that never came back.
