How Airplane Cabin Air Can Get You Sick

Cabin ventilation air comes through the engine. So, if there's an oil leak, engine oil mist -- containing neurotoxins -- can seep into the aircraft. Though relatively rare, it has happened on commercial flights, triggering neurological symptoms like severe headaches, tremors, and dizziness in crew members and passengers.
