    Default Plane breaks through ice

    About time to get those planes off the ice, eh? There are still quite a few parked on Fire Lake here in Eagle River.

    The wheels went through with a PA18, but they walked off the ice? An 18 weighs what?..1200# empty. Sounds to me like they broke through a thin layer of overflow over the ice.

    The story indicates that it "sank further into the ice".

    We came across a 206 stuck in the overflow one year back when I was a surveyor. It was up to the steps on the landing gear (24"?) It sure looked like it fell through the ice, but it wasn't even near falling through. New snow had fallen over the melt water/overflow on top and froze slightly. Frozen snow is nowhere as good as ice as we well know. Plane landed..fell through the top layer. Stuck 206=heavy!! I still don't know how they got it out.

    Default math

    1200# on not much more surface area than your boots. Add in the 2 people and a bunch of gear and you are probably at more like 1800 or 2000#. You can figure out the loading per square inch, but take my word for it, its MUCH more than a person walking. It can happen to anyone (in southcentral anyway). Unless you quit flying the ice early (or are phychic). It wasn't overflow, by the way. A friend went through in the middle of winter a couple years ago. Hit a place where a spring ran under the ice.

    Read the story now - they've updated it with details. The plane went completely though and the fellas had to swim 8-10 feet to climb onto ice. Divers were necessary for retrieval, as was a helicopter. This was no mere overflow soaking.
