Thank you, Mr. Chair.
My question is for both Mr. Turnbull and Mr. Robinson. However, it may be more for you, Mr. Turnbull, given that you are in charge more specifically of issuing certifications.
The MCAS system is recent, I believe. It was installed in the 737 MAX planes. Considering that it was a new system, I imagine you had to concern yourself with this system from a validation and certification perspective.
Can you tell me how the problem that struck the 737 MAX planes could have gone undetected?
