Stevie: stat corrected.
"I totally agree that if people want to risk their lives flying single-engined over water, rotary or fixed-wing, then the CAA should let them get on with it. "
With helicopters, according to the stats, the risks appear to about even whether it's single or twin. Although I'd be the first to admit that there are more twin miles over water than single.
Agree with the focus on numbers - I just hope the CAA have read their own stats before drafting the proposal.
