Vendee. Looking at your location, you were probably engineering the aircraft I was flying. I agree it's not claptrap, and I think we probably know a few people in common who suffered brain disease. "Possibly" (avoiding litigation there) caused by organo-phosphates. Like smoking, one person can be a 40 a day type and live to a ripe old age: another can have one cigarette and die of lung cancer. Susceptibility I suppose, but unnecessary exposure isn't healthy. I was only flying it for some four years, but I do know others who clocked up well over twenty years.
