>"legally, no one has ever decided whether a journey into space technically counts as leaving the United States." That gave me a good laugh. Shouldn't it definitely count? You're zipping over every country on earth while you're in orbit so you definitely left! But if you take off and land in the US, did you _really_ leave? You don't go through customs and immigration for every country you fly over when you're in an airplane, and generally aren't legally considered to have "visited" them. So, wow, good question.
