Big al,
seemed to remember an article in "The Telegraph" aprox a year ago, listing dangerous sport league table, but can't remember exact details.
The caa recently held a "safety evening" at our local club, they reckoned on one fatality per 60,000 hours, in general aviation, but again, details are scant.
Sounds safer than sitting on the couch, getting fat, or smoking 20 a day though !
