- I'm keeping that. It'll be handy even if I never use it.
Not correct. Vapour trails are just that, vapour from condensation. Planes' toilets get emptied at airports.
Yes, the vapour trails you see are just water but it's incorrect to say aeroplanes don't cause pollution.
What you don't see are the by-products from the combustion of aviation fuel ( kerosene ) which are the harmful emissions such as - oxides of nitrogen, sulphur dixoide, carbon monoxide, hydrocarbons.
Typically an aircraft will use 50000 kg of fuel to cross the Atlantic and will produce 60000kg of water vapour, 16000kg of Co2 and about 750kg of the other nasty stuff combined. That's a lot of crap out the back !
