Whoa, this is something I hadn't thought about. What if you were in an airplane and flew through the totality of the August 21st solar eclipse? It could happen. If you were on the right flight at the exact time and place. Come to think of it, the odds are pretty small. And your pilot would be aware of the eclipse anyway. This is the latest from Randall Munroe at xkcd. Go to the comic page to check out the hovertext punch line.
