As an expert in the field of aviation and environmental science, I can provide a comprehensive answer to your question about what airplanes release into the air.
Airplanes, like any other combustion engine-powered vehicles, emit a variety of substances into the atmosphere. The primary emissions from aircraft engines are the result of the combustion process that powers the aircraft. Here are the main components that are released:
1. Contrails (Condensation Trails): The white streaks that you see behind an airplane in the sky are actually artificial clouds known as contrails. This phenomenon occurs when the hot exhaust gases from the plane's engines come into contact with the cold air at high altitudes. The water vapor in the exhaust condenses and forms ice crystals, creating a visible trail. Contrails can persist and spread out, sometimes forming cirrus clouds that can last for hours.
2. Carbon Dioxide (CO2): The combustion of jet fuel in airplane engines produces carbon dioxide as a byproduct. CO2 is a greenhouse gas that contributes to global warming and climate change.
3. Water Vapor (H2O): In addition to the water vapor that forms contrails, water vapor is also a byproduct of the combustion process. It is released into the atmosphere and can contribute to the humidity of the surrounding air.
4. Nitrogen Oxides (NOx): These are a group of gases that include nitric oxide (NO) and nitrogen dioxide (NO2). They are formed during the combustion of jet fuel and can lead to the formation of smog and acid rain.
5. Sulfur Compounds: Sulfur dioxide (SO2) and other sulfur compounds are also released during the combustion of jet fuel. These can contribute to the formation of acid rain and have adverse effects on human health and the environment.
6. Carbon Monoxide (CO): This is a colorless, odorless gas that is produced as a byproduct of incomplete combustion. It is a toxic gas that can contribute to air pollution and health problems.
7.
Particulate Matter: Small particles, including soot and ash, are released into the atmosphere. These can have negative impacts on air quality and human health, particularly in the respiratory system.
8.
Unburned Hydrocarbons: These are hydrocarbons that have not been fully combusted and are released into the atmosphere. They can contribute to the formation of ground-level ozone, another component of smog.
9.
Sound Emissions: While not a chemical release, the noise generated by aircraft, particularly during takeoff and landing, is a significant form of environmental pollution that can affect wildlife and human populations near airports.
It's important to note that the aviation industry is continuously working on improving fuel efficiency and reducing emissions. New technologies, such as more efficient engines and alternative fuels, are being developed to minimize the environmental impact of air travel.

Those white streaks planes leave behind are actually artificial clouds. They're called contrails, which is a shortened version of the phrase --condensation trail." Airplane engines produce exhaust, just like car engines do. As hot exhaust gases escape from a plane, the water vapor in the fumes hits the air.
