Boeing's CEO has resigned amid mounting safety concerns and production problems that have eroded confidence in the iconic aerospace company. The departure follows a series of incidents including a door plug blowout on a 737 MAX and manufacturing quality issues across multiple aircraft programs.

The company has halted deliveries of its 737 MAX while investigators examine production practices. Airlines that had counted on new aircraft deliveries are scrambling to adjust schedules and capacity plans.

The FAA has imposed strict new oversight requirements and is considering whether to limit Boeing's production rates until systemic issues are addressed.
