Over the weekend, the Federal Aviation Administration (FAA) grounded flights on all Boeing 737-9 Max planes following a harrowing incident on Alaska Airlines flight 1282 in which a plug door near the rear of the plane blew out at 16,000 feet, six minutes into a flight from Portland, Oregon, to Ontario, California, causing the cabin to lose pressure. Oxygen masks were deployed, and passengers described a rough ride as the plane quickly returned to the Portland airport; no one was seriously hurt, but several of the 177 people aboard were treated for minor injuries. The incident prompted a sweeping grounding of most of the 215 Boeing 737-9 Max planes that were flying worldwide.
