A former BA Pilot who was retired on health grounds is starting a public campaign to make everyone aware of the dangers of unfiltered bleed air used for cabin and cockpit air.
The article in todays UK Daily Mail
http://www.dailymail.co.uk/pages/liv...n_page_id=1770 details how toxins from engine oil are found in cabins and in blood when secret testing was done.
It is a long article so I haven't copied it here but I can if needed.
OK, it is also promoting a book, and a movie, dvd and a TV show, but is there basis for this scare?
