Thank you.
I have a couple of questions for you, Dr. Fergusson. I've really enjoyed your presentation and your answers to the questions that have been put forward by committee members.
In one of the exchanges, you mentioned that the greatest challenge for the Canadian Forces, and the greatest threat to Canada, is the aerospace threat. What is that threat you're alluding to? And why is it so important that we have that capability to defend the Canadian interest?
