Anne Gorrick and I were riding around in a small, slow-moving, blimp-like airplane, circling Manhattan, looking for a place to land. I was concerned about maneuvering the plane in between buildings, but Anne seemed totally confident and relaxed about it (she was the pilot). As we started to descend, it occurred to me, and so I said to her, “. . .you know, I think one is supposed to have a license to drive an airplane.” And then: “what should we say when the air traffic controllers call?”
