Flight safety could be “degraded” because pilots are breathing contaminated air, a study has warned.
Researchers at the University of Stirling said there was a “clear link” between being exposed to the air on planes and a variety of health issues.
Aircrew who took part in the research reported headaches and dizziness as well as breathing and vision problems.

Unfiltered breathing air is supplied to aeroplane cabins via the engine compressor.
