New York CNN  —  Boeing has agreed to plead guilty to one charge of conspiracy to defraud the United States and potentially pay up to $487 million in fines to avoid prosecution, the Justice Department said in a court filing Sunday evening. But that fine is a fraction of the $24.8 billion that families of crash victims wanted the aircraft maker to pay. The families of victims of two fatal crashes of the 737 Max oppose the deal, the department said.
