Summary:
- Fume events, where toxic fumes enter the cabin of an airplane, are becoming more common. This can happen when engine oil or hydraulic fluid leaks into the air supply.
- These fume events can cause health issues for passengers and crew, including nausea, headaches, and breathing problems. Some people have reported long-term effects as well.
- Airlines and regulators are working to address this problem, but more needs to be done to improve air quality and safety on airplanes.
