Relatives of the victims of two fatal Boeing 737 MAX crashes are urging the US Justice Department to take action against the planemaker, seeking a fine of up to $24.78 billion and pushing for criminal prosecution.

The families argue that Boeing’s actions constitute the deadliest corporate crime in US history, justifying a maximum fine and enforcement of safety measures. The Justice Department uncovered violations of a deferred prosecution agreement following fatal crashes in 2018 and 2019, leading to renewed calls for accountability.

The families suggest suspending a portion of the fine if Boeing commits to safety improvements under an independent monitor. They also demand criminal prosecutions for responsible corporate officials and emphasize the need for justice in the wake of the tragedies that claimed 346 lives.

The global grounding of Boeing 737 MAX planes underscores the gravity of the situation, with concerns over the MCAS safety system persisting. As the deadline for decision approaches, the families and advocates are determined to secure justice for the victims and prevent future tragedies.
