Funny story. A classmate in flight school at Rucker, 1968, had a scar he said was appendix, a week before graduation we took a final physical. A doc said it wasn't appendix, what is it? He said spleen, which is disqualifying for pilots. They had him before a board the next day, he told them that he obviously could fly and he was going to Vietnam and probably die anyway so why kick me out to spend $ training me on something else. He graduated, survived, took a commission and retired as an LTC.
Then there was my best bud who flew over there for a year, he took a flight physical when he got back and was permanently grounded due to being color blind. I had another friend who had his eye shot out, about a year later he got back on flight status, the only 1-eyed pilot I ever knew.
In other words get on them. Every VA clinic has audio chambers and every pilot I knew cheated like heck on hearing tests, including me.

80% high frequency hearing loss cost me my Marine Corps Scholarship in '84. Navy Doc at the MEPS in Houston said "Nope" when I was taking physical to go camp between my Soph and Jr year. Took hearing test 7 times.

I offered to sign a waiver because they were afraid I would claim hearing loss disability later on. Col. Johnson in the Trigon got me an interview with CMC PX Kelly when he came to A&M for Commissioning. We pleaded my case to him. Again I offered to sign a waiver. Kelly told me "Son, there are a lot of things I can overcome but a Navy Doctor isn't one of them"...


D&C fighter the rest of my four......

Had this been during the wars in Viet Nam or Iraq/Afghanistan it would probably had been a different outcome.
