âEagle,â the US Park Police helicopter, flew to Great Falls on the Potomac River last Saturday afternoon to assist with the rescue of an 18-year-old man whoâd fallen into the riverâs swift-flowing waters. Although he managed to get to a rock in the rapids, he was unable to return to the shoreline. Fairfax County firefighters threw him a life vest and helmet, but decided that hazardous river conditions precluded a rescue by boat. The only alternative, therefore, was to extract him via a helicopter hoist. Pilot Keaton Wright brought âEagleâ to a hover 60 feet above the falls and rescue technician Chris Perkins lowered a Billy Pugh rescue device to the man. He was hoisted safely in the helicopter and brought to shore.
