The Cold Front

This 1943 military training film was ordered by the U.S. Navy due to the number of planes that were being lost due to flying in bad weather conditions. The animation covers aspects of flying in front, behind, and within cold fronts.

At the start of World War II, the Disney Studios were taken over by the military as part of the war effort. Taking advantage of the talent that hadn't been shipped off to the war, Disney produced a number of shorts for the armed forces, basically educational and morale shorts. This was one of those shorts.
