Aircraft Pollution
I recently had a discussion with someone about aviations contribution to global pollution.
It was down the lines of aircraft are big and burn loads of fuel so create lots of pollution!
I was trying to agrue about the gas turbine being extremly efficent and clean. I also tried to argue about the fact that fuel costs money and is heavy so the aim is to squeeze every last joule of energy out of the combustion.
My best tech lecture was not to be taken.
Can any one give me some hard facts and figures I can quote to defend aviation, or to prove me wrong!
I am not talking about noise pollution but chemical.
Thanks for your help.
