Your average car doesn't use about 10 tons of fuel per trip
(100 tons if you're talking about a 747 on long haul)

So what's that per passenger mile?

Who cares? Its the same amount of C02 being released whether its full or empty.
If there was no flight most of the passengers probably wouldn't make the trip
or would use a more efficient train.

nor do they inject their
pollution direct into the stratosphere.

Jet-A fuel is basically kerosene, one of the cleanest fuels to burn under
pressure. A Jet Engine is one of the cleanest ways to burn it.

Early jet engines were filthy. Anyone who's seen a 707 or concorde at
takeoff can remember the dirty trails of pollution they left behind. The
latest ones are cleaner but then so are the petrol engines when combined
with a catalyst.
