 So in the future, we might have a better idea of whether planes are experiencing more turbulence. Is there another way we can look at it in the meantime if we're worried about people being injured? Yes. Well, injuries are, of course, a proxy for turbulence. And we do have a long record of injury statistics. We know that the serious injury rate from turbulence is about one serious injury per one million flight departures. So you'd have to take one million flights for just one person on one of those flights.
