He then said that Boeing would approach the investigation first by "acknowledging our mistake." "We are going to approach this with 100% transparency every step of the way. We're going to work with the NTSB which is investigating the accident itself to find out what the root cause is." Calhoun, who has been at the helm of Boeing since Jan. 2020, post the 737 MAX crashes in 2018, also acknowledged that Boeing is at a "very anxious moment" with travelers who will now be questioning whether or not they feel comfortable flying in the 737 MAX 9 jets. "We need to know that we are starting at a very anxious with our customers. We simply have to deal with that reality. So it's going to be a lot about transparency."
