Wing Man

Co-pilot Travis Goetzinger sweeps frost off of the wings of a Twin Otter airplane in preparation for takeoff in April 2007. “Frosted wings can decrease lift by 30 percent and increase drag by 40 percent,” he said, making it difficult and sometimes dangerous to fly. Goetzinger was part of a team that flew scientists from WHOI and other institutions to the North Pole to install ocean and climate-monitoring instruments.
