oh really?

The quantities produced each Shuttle launch are significant, and include a total of 56,000 kg of aluminum oxide and 35,200 kg of hydrogen chloride, and 76,800 kg of carbon dioxide. There is a significant acid deposition near the launch pad that is closely monitored and tracked. The aluminum oxide dust particles form nuclei with water vapor, and results in rain. The rain then absorbs some of the HCl to produce acid rain.
