Turbulence is the ghost in the attic of air travel—the bump and shake and rattling groan that we do our best to ignore, though it sounds like it wants to kill us. Most of the time, it hovers over mountains and in storm clouds, easy enough to avoid. Pilots can see bad weather lurking in the distance hours before takeoff, glowing like a wraith on their digital maps. If it moves, the plane’s radar can still spot it eighty miles ahead or more. But the updraft that struck Flight SQ321 was of a more sinister sort. Although it came from the storm clouds below, there was seemingly no rain in it for radar beams to reflect against. It was like an invisible speed bump in the sky.
