Passengers on board a Korea Air flight last weekend were treated to an unplanned 26,900-foot descent, resulting in several injuries. Seventeen passengers on the flight from Incheon to Taichung required medical attention for everything from hyperventilation to eardrum pain, according to reports.
None of the injuries were serious, thank goodness. The controlled descent was due to a pressurization fault in the Boeing 737 MAX 8 airliner. The pilot had to take the plane below 10,000 feet, where there would be enough air for passengers to breathe since the famous in-case-of-emergency masks provide only enough oxygen for 10-15 minutes.

The emergency was that the plane was losing cabin pressure, and there is barely any oxygen at a typical cruising altitude of around 35,000 feet.
What caused the pressurization problem? I’ll get to that in a moment.
In March of this year, the FAA announced it wants “inspections of Boeing Max planes for wiring flaw that could lead to ‘loss of control.’“
Two Boeing 737 MAX 8 planes crashed in 2018 and 2019, killing all on board both flights. The culprit was a fault with Boeing’s Maneuvering Characteristics Augmentation System, or MCAS, and the lack of training at some airlines to deal with it. To put it in the simplest terms, MCAS was a software patch to make the 737 MAX 8 handle like older model 737s, even though its all-new engines gave it different handling characteristics. When MCAS failed, the plane stopped responding as expected, leading to two deadly crashes.
