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 more fuel-efficient engines compared to its predecessors, aiming to reduce operating costs for airlines. The 737 MAX was introduced in 2017 but faced significant challenges after two fatal crashes in 2018 and 2019. These incidents led to a worldwide grounding of the aircraft, prompting investigations and safety reviews. The 737 MAX was cleared to return to service in late 2020 after extensive modifications and regulatory approvals.
