Co-pilot Travis Goetzinger sweeps frost off of the wings of a Twin Otter
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
difficultand sometimes dangerousto 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.
