US senators grill Boeing CEO Dennis Muilenburg over 737 MAX crashes, calling the planes ‘flying coffins’
- Lawmakers seek answers about whether aerospace giant concealed information about critical flight system
- Families of victims in Lion Air and Ethiopian Airlines crashes invited to hold up photos of relatives at hearing

Boeing CEO Dennis Muilenburg faced withering questions from US senators on Tuesday about two crashes of 737 MAX aircraft and whether the company concealed information about a critical flight system.
“We have made mistakes, and we got some things wrong,” Muilenburg conceded.
Some members of the Senate Commerce Committee cut Muilenburg off when they believed he was failing to answer their questions about a key flight-control system implicated in both crashes.
Boeing successfully lobbied regulators to keep any explanation of the system, called MCAS, from pilot manuals and training. After the crashes, the company tried to blame the pilots, said Senator Richard Blumenthal.
“Those pilots never had a chance,” Blumenthal said. Passengers “never had a chance. They were in flying coffins as a result of Boeing deciding that it was going to conceal MCAS from the pilots.”
