A Coast Guard HH-65 crew from Air Station Traverse City, Mich., used their helicopter’s rotor downwash to clear and break up ice shelves stranding a small fishing boat on Lake Michigan on April 11. The 16-foot boat became stranded in ice floes that pushed it away from shore. It took the HH-65, hovering at 50 feet, about 45 minutes to clear a path back to shore for the boaters.
