Part 2/10:
In May 2023, Alaska Airlines temporarily grounded its fleet of Boeing 737 Max 9 aircraft due to emerging safety concerns. The 737 Max family had been expanded to accommodate more passengers, thus necessitating additional safety features, including several emergency exits known as Mid-Exit Doors (MEEDs). While some airlines planned to utilize the full passenger capacity, others opted for a more spacious configuration, leading to the creation of "door plugs" for the MEEDs.
