Okay. Thank you.
You indicated that you were prepared in advance for this event. Obviously, you have an emergency operations centre that was stood up. However, clearly, there were more planes inbound. The airport was completely closed, I understand, on the 19th in the afternoon and evening. As a result of no gates being available, we saw planes on the tarmac, which you've referenced.
Is part of your review to determine...? Did you talk to Nav Canada?
Were there flights that were allowed to proceed to YVR that should have been held at their origin, so that you didn't have the issue of that many planes sitting on an apron that was unable to disembark passengers?
