No, I do not.
I greatly regret what has happened and huge sympathies go out to the families, obviously, with these tragic accidents. I stand before you today being fully confident that we made the right decision with the information that we had. We did do our usual due diligence through our normal tried and true validation process that we've applied to many foreign aircraft. We did our job.
The concern that we're dealing with here is the after-discovery of some of the functionality of the system and its behaviour in certain failure conditions, which was not made readily apparent to us during our validation process, despite our efforts.
