So what other leaps in safety have come from unfortunate happenings
The list is endless, as
DAR comments, "There are lessons to be learned from every accident". The one that is closest to me was a very good friend, an instructor I'd had, and attended me at my wedding, who had the rotor head depart from his helicopter while in flight, killing all four on board. The aircraft was fairly new type on the market and cause was found to be a design fault, subsequently rectified of course. Personally spent 12,000 hours flying the same type of aircraft and often while in the cruise used to think of him and what his final moments must have been like.
