the high altitude emissions of aircraft are not particularly good for the environment. Whether this is a concern to you or not, until it is established with certainty that we don't need to worry about it - we probably should given the potential consequences.
No, it's not a concern for me. Bring back Speys, JT8's et all. I'm off to fill up my 5.0l SUV now.
Air travel enjoys many priveladges over other forms of transport? Do you work for a carbon offset company? Greenpeace?
those who DO have something to do with aviation are likely more focused on their own interests than those of everybody else.
Of course - we are on a pilots forum not a tree huggers one. But tell me, how will you travel on vacation this year? Or for business will you drive to Russia from the EU? Perhaps the train?
