"Boeing 737 Max 9 Incidents: Loose Hardware and Mid-Flight Drama Plague United and Alaska Airlines"

Both Alaska and United airlines have found problems with door plugs on their Boeing 737 Max 9 jets after an "explosive" blowout of the same piece of fuselage on an Alaska flight. The National Transportation Safety Board is investigating the incident, which involved a door plug becoming dislodged due to loose hardware. The cockpit voice recorder from the flight was erased, hindering the investigation. European airlines continue to fly Boeing 737 Max 9s, while U.S. airlines have grounded their planes. This incident raises concerns about the safety of the aircraft and the need for improved recording capabilities.
