some things wrong. we're improving, and we're learning and we're continuing to learn. >> do you think muilenburg's role as ceo is tenable going forward, miles? >> it's going to be difficult. obviously, there's always been a shake-up. he's already been demoted from chairman. his head of commercial aviation has been replaced. you know, maybe this is just a matter of timing. i don't know how this is all going to play out, but generally speaking if there are criminal charges, they're brought forth against individuals, not the corporation. that's typically how it goes. you just don't know where this is headed but it sure seems like there's a lot there for potential criminal case. having said that, there -- boeing has plenty of other troubles separate from that as far as the civil litigation. hopefully, in the end, this will lead to significant changes in the regulation so that the faa is able to inspect and understand these highly complex aircraft as they're developed. >> that's the positive here.
