Here is the latest discovery by Chris Fly King
"This day was one of those 2 hour window days. The wind was going from s/w to a north wind and then back to s/w again all in a matter of a few hours, so I had to be there right on the switch. And as we know, these Scandanavia weather patterns don't always work out. I made the call, dropped some plans and fortunately everything came together."
