I have to agree with MOR on the points about scientific research. It is all very well expounding on this or other forums about second hand experiences or even first hand experiences where there was no conclusive proof as to the source of the experience in the first place.
Until there is proper research into the suspected problems no one is going to admit to anything, especially if they may be liable in some way.
Dramatic statements on here and infuriating responses to people like MOR who are pointing out to you the flaws in your arguments only serve to show you up as over sensitive drama queens. You may not agree but that is how it appears to those of us who have not had any experience of contaminated air events and have flown some of the types that are supposedly more likely to have them.
I think that it is agreed that there should be more research into the problem. However, you first have to convince someone to part with the money to fund the research. Ranting on here without acceptable evidence is a waste of time and effort. If you can agree that it hasn't been proven but there MAY be a problem, then you are at least one step nearer to finding out, one way or another, as to what all the fuss was about.
