I clicked through to Cowboy's link on the Cape Gibson and noted this photo:

which reminded me all too intensely of the days when they used to do to ME (in a bosun's chair) what they are doing to that net full of cargo. When I was the doctor for a frigate squadron, there were essentially 2 ways to get from one ship to the other out in the middle of the ocean: helocopter or highline (as in the picture). I don't much care for flying so I chose highline when feasible.
