Boeing CEO Dennis Muilenburg touted the software upgrades to the company's 737 Max planes this week and said that he would trust the planes with his own family's safety.
In an interview with CBS News on Wednesday, Muilenburg said he would "absolutely" put his own family on board one of the jets.
"You'd put your family on a 737 Max?" asked CBS's Norah O'Donnell.
"Without any hesitation. Absolutely," he responded.
"We clearly fell short, and the implementation of this angle-of-attack disagree alert was a mistake, right, we did not implement it properly," he added, referring to a system in the 737 Max planes blamed for two deadly crashes in six months that killed more than 300 people.
"We're confident in the fundamental safety of the airplane," he added.
Muilenburg's remarks come as Boeing is seeking reapproval from the Federal Aviation Authority for the 737 to resume commercial travel in the U.S. after it was grounded around the world earlier this year following the second deadly crash, which involved an Ethiopian Airlines jet.
In the meantime, the Securities and Exchange Commission (SEC) has opened an investigation into whether the company adequately informed stockholders of problems with the plane, while the FBI has joined the Department of Transportation in a criminal probe into the plane's certification.
