This comment sounds familiar....until the mindless author gets sick
But do note that the "author" was actually someone else making comment on Mr Learmounts blog (to be fair to him).
However the parallels the blog draws between the tobacco industry and the aviation one are a bit tenuous. When litigation finally succeded in the mid 90's it was uncovered that there were numerous memos flying around that showed the industry was well aware of the damaging nature of tobacco smoking. The industry denied any link throughout and actively worked against any researcher who took a contrary view. Richard Doll showed in 1954 that there was a link yet the industry tried to rubbish his research at every turn. My view is that the airline industry and the campaigners are stuck in the position of not having enough evidence to show a definitive link as there has been no peer reviewed research which does show this. Individuals may win court cases based on law intended for other industries but no wide-srpead precedent has been set saying that the aviation industry is aware of the problem but are actively working to cover it up.
Please note that I am not trying to say there is or is not a problem here other than at the moment there is not enough research done which can be used one way or the other.
