Aerospace manufacturers like Boeing and Airbus cannot produce airplanes fast enough to meet demand despite what the Wall Street Journal calls "one of the industry's steepest production increases since World War II." The run up in demand is partially the result of fast-growing airline industries in the Middle East and China. Manufacturers will need to increase production by 30% to meet current orders, and such booming demand is one sign of a healthier global economy.
