 A modern aircraft has a much better response to turbulence than one of the previous generation. It moves up and down less. So lots of things are changing. More turbulence in the atmosphere sounds really bad, doesn't it? And nervous flyers hate it. But there's an optimistic message here too, which is that we can get better at avoiding it, and indeed we are. 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?
