I was only a few km away from the accident site(on the ground) when it happened. Around that time I was caught in some of the heaviest rain i've experienced. At one stage I reakon the vis would have been less than 100metres. Certainly not the best weather to be stooging around in when your not sure where you are.
I took have never flown one but spoken to people that have, and they all commented that they can bite like the best of them if not treated right.
