“I talk to the airlines, and they realize there is a looming threat,” Paul Williams told me. “But it’s quite distant for them. They see it as decades in the future. The people really taking notice are the designers. The airplanes they’re designing now will still be flying in 2050, so they can’t wait. And here is a bit of a shocking thing: the design and certification standards for air worthiness are based on turbulence measurements from the nineteen-sixties. It’s reasonable to ask, Are those standards still fit for the purpose? Will they still be fit for the purpose in 2050?”
