I lost my Kidneys 6 years ago after 17 years on the 146. Up till then, I was a sceptic on the fumes issue, but I had a rare condition (Good pastures syndrome) which shut down my kidneys in a week. The only clue I had was a consultant asking me if I had been in contact with oil. Apparently the organophosphates in the oil acts on the immune system and can give a variety of conditions, in my case , kidney failure. It is well documented in the farming world as the old sheep dip had the same effect. I know of many colleagues ex 146 that have been seriously affected in various ways, also including the 757. Don't tell me that Boeing went to the expense of using independent compressors for aircon in the 787 out of the goodness of their hearts! Anyway, I had a transplant two years ago, and am back to a normal life, still flying in a Jodel.
