Delta Air Lines has learned that summer is a good time to prepare for winter — and how to de-ice planes so they can keep flying safely in freezing temperatures.Every summer, Delta brings about 400 workers to Minneapolis to a three-day summer de-ice "boot camp.” They go through computer-based training, watch demonstrations by instructors, and then practice spraying down a plane — using water instead of the chemicals found in de-icing fluid.
