I'd love to go to space. I would love to peek out a giant window and look back at the blue marble. There's no question; I'd love to do that.

Furloughing a bunch of air traffic controllers has a pretty easy-to-predict effect on air travel: It causes delays.

The glamour of air travel - its aspirational meaning in the public imagination - disappeared before its luxury did, dissipating as flying gradually became commonplace.
