Agree on the hitting and fishing. He had great eyesight and reflexes, ideal for a fighter pilot, but he never really delivered on the fighter part of it. He was shot down--but was still able to "limp" back to his base--by antiaircraft fire while on a bombing/strafing raid in Feb 1953, near the end of the Korean War. He never flew in combat in WW II, which was undoubtedly one of the reasons he was called up for the Korean War, which he bitterly resented because he was an inactive reservist and felt active reservists should have been called before him. He also tried to avoid service in WW II by saying he was the sole support for his mother.
Nevertheless, Ted Williams was a rarity in that he served in two different wars while also being one of the very best hitters in MLB. In both wars he was in fact a trained fighter pilot--an instructor in WW II and John Glenn's wingman in the Korean War. Yes, he griped some, but he was unquestionably a patriot.
