A de-icing vehicle removes snow from the left wing of a transient C-17 Globemaster III, assigned to the 62nd Airlift Wing Joint Base Lewis-McChord, Washington, prior to departing Dover Air Force Base, Delaware, Feb. 11, 2021. Because snow and ice can change the shape of an aircraft's wings and tail, the de-icing process is very important in ensuring a smooth and safe flight.
