A US judge has rejected a plea deal involving Boeing tied to two fatal crashes, stating it lacked sufficient oversight and accountability for the aerospace giant. The deal, originally agreed upon with the US government, would have required Boeing to plead guilty to criminal fraud and pay a substantial fine. Families of the 346 victims of the crashes welcomed the ruling, emphasizing the need for genuine accountability. Boeing now has 30 days to propose a new plan amid ongoing scrutiny of its safety practices following previous incidents.
