British airlines is accused of exposing cabin crew [bbc.co.uk] to breathing in fumes [wikipedia.org] mixed with engine oil and other toxic chemicals like TCP [wikipedia.org], an organophosphate known to be dangerous to human health in high enough quantities. But the Civil Aviation Authority (CAA [wikipedia.org]) says incidents of smoke or fumes on planes are rare and there is no evidence of long-term health effects. Safety reports submitted to the CAA show that between April 2014 and May 2015 there were at least 251 separate incidents of fumes or smoke inside a large passenger jet operated by a British airline. Pilot Richard Westgate died in December 2012, aged 43, after complaining of long-term health problems. The coroner said the body "disclosed symptoms consistent with exposure to organophosphate compounds in aircraft cabin air". A similar case is 34-year-old Matthew Bass who died in 2014.
