I posted on an article about the same subject that was reported on in the Daily Mail on the 8th February 2008, but the thread was moved to SLF. Shame because this report was specifically about a pilot who had been retired on health grounds due, he suspected, to toxins in the planes air supply.
The thread is here -

Definitely worth reading the Daily Mail and Telegraph article - and I shall watch the Panorama program as well.
What is of course annoying here is that the whole thing is being covered up by the airlines and governments! Proof by covert testing and numerous reportings of toxic air are just being swept under the carpet by the CAA and the UK gov for starters!!
