Adam Greenfield takes astronaut lessons:
"Flying out of Incheon today, on our way back to Tokyo, our flight hit an unexpected void just as I climbed out of my seat to let Nurri into the aisle, and dropped what must have been hundreds, if not thousands, of feet of altitude in seconds. For a brief but endless interval, we - alone among the passengers - found ourselves free of the grip of gravity, Nurri actually floating all the way up to the cabin ceiling before the (auto?)pilot found a layer of clear air and we settled back to the deck."
