Thin air and even radiation exposure are insignificant in comparison
to
the problems associated with engine oil seeping into the aircon. Some
airplanes are a lot worse than others, the older Rolls Royce powered
757s and TriStars being the worst with the Lycoming Powered Bae 146s
not
far behind. Almost all have the problem to some extent or another.
All jet oils, particularly Mobil, contain huge amounts of nasties
such
as organo-phosphates which affect the central nervous system and are
extremely hard to get rid of. Almost all airliners have this problem,
however, and every time you fly on one you get a certain amount of
this
crap in you.
If you ever get on an airliner and you get a certain sour "smelly
socks" smell, that means there's an unusually high concentration and
that the engine seals arent doing their job. If you get enough in
your
system during a flight, you'll probably have runny eyes and
irritation
in your throat and sinuses. If you get a high enough dose in one
flight,
you'll also have a nice tingly headache right at the top of your
skull.
A major dose will bring about a night wither on, or kneeling in front
of
the toilet...
It's a huge problem that the airlines and manufacturers are keeping
as
quiet as possible about because of the huge liability exposure they
have. The next generation are eschewing bleed air driven
pressurisation
and going to seperate supercharger systems. A lot of older turboprops
used this system as well as a small number of jets. The 787 will have
this system.

I'll forward this to all the airlines and let them know their pilots
are
concerned enough to be posting to the world.


That might help, you never know.
