Flight or Invisibility?

Recently I listened to this bit on This American Life where John Hodgman surveys people about which superpower they'd pick if they could be the only person in the world with either flight, or invisibility? And why would they pick it.

What surprised me is that none of the people he included in sound bites, nor John Hodgman himself, ever even alluded to most of the things that came to mind first to me. So before you read what's below the cut here, I'm curious: What do you think? Which would you pick, and why? What would you do with it?

Edit: The reason I'm asking this question is to find out what you think are the reasons why you might want flight, why you might want invisibility, and why you'd pick the one you pick? (Before you read further and see what came to mind when I thought about it)

( Well, okay, what came to mind first was... )

I'd certainly expect some of the people in the radio piece to have very different views from mine, but I thought the things that came to mind for me were obvious enough, or plausible enough, that I'd at least hear some of them, from someone. Now I wonder whether I'll see any of them from any of you who read this, before you read my whole post.
