WATCH: Boeing CEO Apologizes to Families of Crash Victims Accusing Him of ‘Deadliest Corporate Crime in US History’

Boeing CEO Dave Calhoun testified in front of members of the U.S. Senate on Tuesday to defend his company’s safety record after several incidents and fatal plane crashes. Before he began, he stood to face the families of those crash victims to apologize to them.

While still seated, Calhoun said, “Before I begin my opening remarks, I would like to speak directly to those who lost loved ones on Lion Air Flight 610 and Ethiopian Airlines Flight 302.” Both of those flights involved Boeing 737 Max planes.

Calhoun then stood and turned around to face those families in the gallery, many of whom held up posters with images of those who had perished:

I would like to apologize on behalf of all of our Boeing associates spread throughout the world, past and present, for your losses. I apologize for the grief that we have caused. And I want you to know we are totally committed in their memory to work and focus on safety for as long as we are employed by Boeing.

He ended with the words, “I’m sorry.”

According to Politico, some in the gallery shouted back at Calhoun, asking “We want to know how they died” and “How could you, Boeing, and the CEO, let that happen.”

Families of the victims of those two flights filed a lawsuit against Boeing with the Department of Justice, calling the tragedies the “deadliest corporate crime in US history.”
