Instead, the emissions, consisting of sodium oxide, would actually soak up carbon dioxide from the atmosphere. This compound would quickly combine with moisture in the air to make sodium hydroxide — a material commonly used as a drain cleaner — which readily combines with carbon dioxide to form a solid material, sodium carbonate, which in turn forms sodium bicarbonate, otherwise known as baking soda. Remember acid rain? Now we will have alkaline rain. Using fuel for planes, that makes exhaust that dissolves the planes might not be a smart idea.
