WarTime ice cream!! Certainly not a smooth italian style Gelato.
WWII bomber pilots did make ice cream mid-flight by attaching a mixture to their planes, relying on the high altitude's cold and the engine's vibrations to freeze and churn it into a frozen treat. This practice was often a morale-boosting activity, though the results were sometimes more like frosty milk than smooth ice cream, and it was sometimes done using modified fuel tanks or other equipment.
How it worked: Pilots would put the ingredients for ice cream, like canned milk and cocoa powder, into a container such as a modified fuel drop tank or an ammunition can.
The "freezing" process: They would then attach this container to the exterior of the plane. The extreme cold at altitudes of 25,000 feet or higher would begin to freeze the mixture.
The "churning" process: The constant vibrations from the flight itself would help to churn the mixture, creating a frozen dessert rather than a solid block of ice.
The results: The final product was often a rough, frosty ice cream, though it was eagerly consumed by the crews.
Why they did it: Ice cream was a popular morale booster for troops, and this method allowed pilots to create their own sweet treats in environments where such luxuries were otherwise scarce.
Other methods: On B-17s, crews used open bomb bay doors as makeshift freezers to chill ice cream mixtures. The U.S. Navy also developed larger-scale methods, such as a floating ice cream factory barge that could produce thousands of gallons of ice cream per day
