One of the keys to gathering data for Operation IceBridge is a highly modified McDonnell Douglas DC-8 jetliner, which NASA operates as a flying science laboratory. This workhorse DC-8 can fly long trips, allowing a suite of scientific instruments to study the Arctic ice sheet, glaciers and sea ice.
