Boeing Co. will pay $2.5 billion to fix a Justice Department criminal investigation and admit employees deceived aviation regulators over safety issues that led to two devastating crashes of the 737 MAX.The settlement, which was filed Thursday in Dallas federal court, would lift a legal cloud that has hung over the aerospace company for roughly two years since the fatal crashes. Federal prosecutors had been investigating the role of two Boeing employees who dealt with the Federal Aviation Administration regarding the design of the 737 MAX and how much pilot training would be needed for the new model.The settlement includes an almost $44 million fine as well as nearly $2.3 billion in compensation to airline customers and families of the 346 people who perished in two MAX crashes.
