Boeing CEO Dennis Muilenburg on Wednesday faced a second straight day of congressional questioning on the aircraft maker’s role in two deadly crashes involving its 737 Max plane. House lawmakers focused on evidence that Muilenburg and other Boeing executives were warned about safety issues connected to the jet before the first crash last October.

Representative Albio Sires, a Democrat from New Jersey, read a worker email sent to the head of Boeing’s 737 production team in mid-2018 that claimed high production goals were straining workers and increased the potential for mistakes. “For the first time in my history with Boeing I would be hesitant about putting my family on a Boeing airplane,” wrote the veteran Boeing employee.Muilenburg said he only became aware of the worker’s concerns after the Lion Air 737 Max crash October 29. He said the 737 production line was working at a “high rate” at the time and the issues raised by the now-retired employee had been investigated and addressed. 
Nonetheless, when pressed Muilenburg said the company never cut back its production of the aircraft even after being made aware of the worker’s concerns.Members of the House Committee on Transportation and Infrastructure also zeroed in on why Boeing decided to only have one sensor on the outside of the plane, with no back-up, to alert pilots when the angle of the aircraft was off. In addition, they asked why the plane’s safety system only gave pilots four seconds to react to take back control of the plane if a malfunction occurred. While acknowledging that Boeing planned to make fixes to the craft, some lawmakers also questioned why the company took so long to come to that conclusion.”Why wasn’t that the way from day one,” asked Representative Peter DeFazio, an Oregon Democrat. “If you can do it now, why couldn’t you have done it on day one.”Muilenburg responded as he had in his appearance before a Senate committee on Tuesday, apologizing to family members of the 346 passengers who died in crashes and admitting that mistakes were make. “We would do it differently if we knew what we know today,” Muilenburg said Wednesday.$15 million in pay and bonus an issueSeveral committee members pressed the CEO to make more changes in the aftermath of the crash, including giving up some of the $15 million in pay and bonus he received last year, out of $23 million in total compensation for 2018.
