The ship knows how to land on its own. Why shouldn't I go skydiving?
Uhmmm. Because it's faster to land in the ship. It's Friday afternoon and if you're not at the government office before it closes, you won't get paid until Monday.
That's a good reason. That's a very good reason. In fact, that's such a good reason I might even be able to resist the bright, shiny temptation of the eject button.
