“The past five to seven years have been very hard on us personally,” Darrel Larson, a vice-president of operations, told me. Larson, who grew up on a farm in North Dakota, has a rangy frame and a folksy manner. We were standing on the floor of the building where the 777 is constructed—the largest factory in the world by volume. It’s a vast, open hangar, two-thirds of a mile long and a third of a mile wide, subdivided by rows of glass-walled offices. A system of tunnels runs beneath it, and a network of rails above, hung with gantry cranes that can lug an eight-ton engine across the floor. The factory runs around the clock, yet it was eerily quiet. The planes are mostly assembled from modules made at other sites nearby, and pieced together in a strictly orchestrated sequence. Shrink-wrapped airplane lavatories were clustered along the perimeter, next to carts full of bins with numbered parts. It was the world’s most sophisticated Lego set.

“Turbulence is one of the great unsolved problems in classical physics,” Larry Cornman, a senior researcher at NCAR, told me, when we spoke in his office. “You have to predict where these things will happen and when, but the equations are inherently nonlinear.” Cornman is sixty-eight, with brown hair, streaked with gray, that hangs below his shoulders. He was dressed in a T-shirt and a tracksuit jacket, and spoke with an offbeat affability—a holdover from Boulder’s hippie days. Before earning degrees in math and physics from the University of California, Santa Cruz, Cornman lived in a Buddhist commune in Northern California for three years. When he moved to Boulder, in 1983, he took a job at NCAR as a part-time computer programmer, and never left. He has since earned eight patents and devised some of the most widely used systems for detecting turbulence.
