Flying while high?

Um... shouldn't this on the to do list?

Toxic fumes on planes are poisoning pilots and rendering them unable to fly safely, say pilots, who are campaigning for "aerotoxic syndrome" to be recognised as a disease.

Two official investigations are being opened after concerns that highly toxic oil contaminants are leaking into cabin air supply on commercial airliners in flight. The UK government is to fit air-monitoring equipment on board aircraft amid increasing concerns that passengers, pilots and cabin crew are being exposed. And 1500 pilots will take part in the first major health study designed to establish the extent of the problem.

"We're basically the canaries – getting knocked down by the fumes first," says Susan Michaelis, a former pilot who believes she was poisoned by fumes from leaked engine oil while flying. She and other grounded pilots launched a campaign for the condition to be recognised, at a meeting at the UK's Houses of Parliament on 18 June.

Compressed air is routinely drawn off engines and supplied to aircraft cabins. If the seal inside the engine is not secure, engine oil can leak into the cabin and contaminating air with toxic tricresyl phosphate (TCP), says Michaelis.
