Thank you, Chair, and thank you to our witnesses for coming today.
I think we all agree that an ounce of prevention is worth a pound of cure. As Ms. Block said, our job here is really to probe as much as we can in terms of how going forward, hopefully, we can avoid this type of tragedy happening again.
Following on the conversation that we've already had this afternoon, I'd like to understand better, in terms of the validation process, to what extent you involve pilots and their feedback. You obviously use pilots and so on. If we could go back to before the first crash, what kinds of conversations does Transport Canada have in terms of listening to the pilots about their experiences and incorporating additional requirements through that validation process?
