What about it?

Quite.

It depends what you mean by 'cleaner' -- catalytic converters make
engines less, not more, efficient in terms of CO2 emissions. What has
made a positive difference is fuel injection. High bypass turbofan aero
engines are more efficient in every way than their low bypass or
turbojet predecessors.

The latest turbine engines are actually little more efficient in the amount of
work done per unit of fuel than a decent piston engine and thats only
when they're running at constant rpm.

Who cares? Its the same amount of C02 being released whether
its full or empty.

But CO2 in the stratosphere isn't a problem. Nor is it pollution.

That is such a cretinous statement thats its hard to know where to begin
with a reply really. Suffice to say the atmosphere mixes and what goes into
the one part won't stay there forever.

If there was no flight most of the passengers
probably wouldn't make the trip or would use a more efficient train.

Let me know when I can catch a train to Canada.

If you're in the USA it shouldn't be a problem. Anyway , obviously for some
trips an aircraft is the only viable option unless a month on a ship is part
of the plan. But there are plenty of short haul flights which could be
dispensed with.

Anyone who's seen a 707 or concorde at
takeoff can remember the dirty trails of pollution they left
behind.

Which isn't in the stratosphere, which is what you were complaining about.

I think you'll find the engines were just as dirty whatever the altitude.

And Concorde using afterburners was very clean...

********. It left a trail of brown NOx that even Stevie Wonder could have
seen.

How strange - an Afterburner is very clean, as it superheats and burns
the fuel almost completely. Certainly the only film of Concorde I can
find with a trail of brown smoke is the day it crashed.

Actually an afterburner just dumps more fuel into the exhaust of the turbine
which then ignites with the left over O2.

the fuel almost completely. Certainly the only film of Concorde I can

You didn't look very hard. This shows it quite nicely:

Kerosene PM10's... not NOx.

I'm sure its a mixture of a whole load of nasty things. Point is - its a long
way from being clean.
