This will indeed be an accident that I shall have a keen interest in. I too have found myself some years ago now in similair situations, out in the Pacific at night in less that ideal wx conditions wishing I was home in bed.
The stress would have been high for the crew, Aero-Med work has it's challenges at times like no other.
As long as everyone walks (swims in this case) away then we can all learn from it hopefully.
