Fuji - indeed. But of what comfort is that when it all goes quiet up front and you can't see the ground?
I was far from 1,000 hours when mine happened (and I know some guys who've had up to 3 in those number of hours), which of course doesn't contradict that the average is 1 in 1,000 hours. The reality is it could just as well happen in hour number one as in hour number 1,000. Or 5,000. Or never in a pilot's flying lifetime!
Something that has kept me alive in 35 years of SEP flying, even ahead of "never take the aeroplane anywhere your brain hasn't already been", is "ALWAYS have an 'out'".
Flying over fog denies you that. I would not be happy to fly with any pilot who accepts, knowingly, a situation where if the engine fails there is no 'out'. Flying over water is a grey area for me this respect, but flying over extensive fog isn't. You have pretty much no chance.
For me, that indicates a non risk-averse attitude. Not a good thing in a pilot IMO.
