US senators attacked the CEO of Boeing - for the planemaker's tarnished safety record, overshadowing his apology to families who lost loved ones in two 737 MAX crashes and acceptance of responsibility after a January mid-air emergency. Senators also questioned the CEO over Boeing's treatment of whistleblowers over the years. The CEO was also grilled about his pay package. The 2023 pay package of Boeing's CEO rose about 45% to nearly $33 million.
