In recent months, Boeing’s share price has fallen almost as fast as its aircraft parts have tumbled from the sky.
There have been a series of harrowing incidents this year involving defects on Boeing planes. Some cases were routine hiccups, but others involved alarming oversights—most infamously, the loose bolts that led a door-plug panel from an Alaska Airlines 737-9 Max to land in the yard of an Oregon schoolteacher on Jan. 5. This latest round in Boeing’s struggle with manufacturing debacles and quality-control problems led CEO David Calhoun to announce his resignation. The Federal Aviation Administration, meanwhile, has cracked down on the manufacturer, limiting Boeing’s ability to deliver new aircraft.
