Airplane travel is nature's way of making you look like your passport photo.

I'm naturally an optimist, but my basis for hope is rooted in my understanding of human nature.

If the only tool we use to analyse what's valuable is a price tag, then those things that don't have price tags begin to look like they have no value.

When Bangladesh refused to renew my passport, I used U.N. travel documents. You can't disown your country.

What would air travel look like if airplanes were thrown out after each flight? No one would be flying in airplanes.

I have always been fascinated with those who try to look over the horizon and see things that are coming at us.
