Fishermen getting stuck on Lake Superior ice is not a new story. Three teenage boys rafted out into the lake off Duluth in the late spring ice of May, 1979. 23 anglers went to sea off Duluth in March, 1993. In most of these stories, the accident evolves slowly enough that rescuers can be notified and come to the aid of all the anglers.
