The Boeing 737 MAX is a family of narrow-body commercial aircraft developed by Boeing. It is designed for short to medium-haul flights and features advanced engines, improved aerodynamics, and updated systems compared to its predecessor, the Boeing 737 Next Generation. The MAX series includes several variants, such as the MAX 7, MAX 8, MAX 9, and MAX 10. The aircraft was introduced in 2017 but faced significant challenges, including two fatal crashes that led to a worldwide grounding in 2019. After extensive safety reviews and modifications, the Boeing 737 MAX was cleared to return to service in late 2020.
