I was a rescue aircrewman in helicopters based out of San Diego during the last part of the Vietnam war. Actually was on the primary recovery helicopter of the final Skylab mission... way cool but in the end a big let down because of the ease of the entire operation. No ear problems after 4 years of active and reserve duty. Still dont have any sign of problems after 30 + years of working on pianos... knock on wood. Cheers RicB
