When I visited the Boeing facility in December, the company was going through a rough patch. The two 737 MAXs that crashed in 2018 and 2019, killing all their occupants, were brought down by the same faulty sensor: it kept telling the flight-control software to tilt the plane’s nose down. After the second incident, the F.A.A. grounded the entire 737 MAX fleet for twenty months. Then, in 2024, another of the planes ran into trouble. It was climbing to sixteen thousand feet over Portland, Oregon, when one of its side panels blew off, leaving a gaping hole in the plane’s left flank. The cabin pressure dropped so quickly that a fifteen-year-old boy had his shirt ripped off his back. It was later found that the panel was missing four bolts that should have kept it in place.
