http://wbztv.com/local/local_story_309115400.html So here is a crew that have had their (maybe) first fume event.
Some of the five crew may be exposed to lesser fume events in the future and then they will begin to feel extremely ill.
Many aircrew have been down this route before them; it's just sad to think that their careers may well be over within a couple of years.
Most people never seem to work out the cause.
