Juan Cole on the future of air-travel

And, you have to wonder whether air travel was not anyway a bubble. It depends on inexpensive fuel, which probably won’t be with us for long. It has a very big carbon imprint, which may soon be illegal. And it is vulnerable to low-tech chemical sabotage. Our generation perhaps, and the next one almost certainly, will have the unprecedented experience of having their world become larger and less accessible, after two centuries during which it shrank and seemed conquerable.
