How safe is the air you breathe on planes? BBC News

17 former and serving cabin crew is planning legal action against British airlines, claiming

 they have been poisoned by contaminated air. Reports submitted to the air safety watchdog

 here in the UK, shows that there are hundreds of so-called fume events, each year - where 

engine oil and other toxic chemicals. May has leaked from the engines into the plane itself.

researches, and not only technical searching.
