10% of miles by planes. And they did that with <4% of the liquid fuel?

And in 2000 planes averaged 38 MPG per passenger mile.

I’d say that our concentration needs to be on electrifying our personal vehicles and improving our rail service for short/medium length trips and not get overly concerned about planes.

When we get carbon neutral biofuels for planes, great, but between now and then just cut the amount of petroleum we burn on the ground. That’s doable right now.
