"Airline Industry Turbulence: Boeing's 737 Max Woes Shake Stock Prices and Safety Concerns"

Boeing's stock price dropped nearly 10% after a door plug blew out of its 737 Max 9 aircraft during an Alaska Airlines flight, leading to an FAA order to ground the aircraft. The incident has also impacted the stock price of Spirit Aerosystems, the manufacturer of the door plug. The NTSB has opened an investigation, and United Airlines found loose bolts on its 737 Max 9 fleet during inspections. Boeing has expressed regret over the incident and is supporting the FAA's decision for immediate inspections. This renewed scrutiny comes after the grounding of Boeing 737 Max aircraft following crashes in 2018 and 2019, and amid pandemic-related challenges and supply chain issues. CEO Dave Calhoun acknowledged the company's ongoing recovery efforts and emphasized the focus on quality processes and transparency.
