There was a compensation scheme in the late eighties or early nineties which I took advantage of even though I held a CAA Class One medical. Mine was on the basis that ASCEU had banned the wearing of helmets whilst crew changing on Pumas at night. The word got around quite a few ex service people locally and one friend who had done national service and was deafish in his right ear got it on the basis of firing a .303 rifle.
I received around £1,350 which I thought was OK at the time. It has stymied me for the £250,000 I could get now.
