whether the credibility can be restored with boeing and david calhoun, the ceo. i reached out to management last night and of course they can't discuss an active investigation, however, they are coordinating, they are working with the ntsb as we said. what the challenge is going to be is when the -- david calhoun matches wits with the faa with administrator whitaker. that's where the real thing is going to happen. that's where this battle is going to start and we are just going to have to see what they come out with. my judgment about the boeing aircraft is that we've got issues that are being dealt with, those are all fairly new issues. so i believe that there's something gone wrong in boeing that can be fixed, but it's going to take a herculean effort on both parts and they're going to have to work together and not make this a battle to make sure these things get fixed properly and put back into service and restore the confidence that boeing once had. >> yeah, that will also be a herculean effort, obviously reestablishing that confidence.
