Toxic Fumes on Planes Linked to Brain, Nerve Injuries
Some planes have a problem where bad fumes get into the air people breathe, like oil and hydraulic fluid.
These fumes can make people sick, with headaches, dizziness and confusion.
Pilots and flight attendants are reporting brain and nerve injuries.
This is happening because air is taken from the engines to keep the cabin pressurized.
When seals wear down, these bad fumes can leak into the air.
Reports of incidents are increasing.
Airlines say the air is safe.
Lawmakers are trying to address the issue.
Reports show an increase in fume events in aircraft cabins.
Pilots and flight attendants report brain and nerve injuries.
The fumes are caused by engine oil or hydraulic fluid leaking.
The 'bleed air' system is the source of the problem.
Incidents increased dramatically in recent years, especially on Airbus A320s.
