I'll go back to my opening remarks, in that the coordination and collaboration between international authorities has been significant from the beginning of this process. The FAA are the certifying authority, but as my colleague Dave pointed out in some of the changes that were just outlined there, I would say that the other three authorities were also leaders in ensuring that those changes were made to that aircraft.
The four authorities together continuously meet and met to discuss this aircraft, to discuss the review of the aircraft and to exchange ideas of the aircraft. They met within the group of four but also bilaterally and trilaterally at times.
Now that we are committed to looking at the reviews—particularly, I would say, the joint authorities technical review that we as well as other certification authorities participated on—we're committed to working with the United States in making sure that those recommendations are implemented in a consistent manner that has harmony across the four authorities.
