I will share any remaining time with my colleague, Mr. Gerretsen.
Thank you to all four of you for being here, for your tremendous work, and for offering us your insight and counsel.
I'd like to start with a question for Professor Byers on the issue of fighter aircraft and the replacement thereof, and I'd like to start with anecdote.
I had the privilege of completing part of my civilian flight training right here in Ottawa, at Ottawa Aviation Services, in a little single-engine aircraft. At the time, Ottawa Aviation Services had a policy of suspending flight operations any time temperatures went below 20°C. They did that, not because of a general lack of capability of the aircraft, but because of the realization that if a student went down in the Gatineau hills as a result of engine failure, she or he would be in serious trouble. That's within a very tight radius of Ottawa. I appreciate your testimony on the single-engine versus twin-engine paradigm, especially given the unique nature of the work that these aircraft are going to be doing in the Far North, not here in the Ottawa area.
I'm wondering if you could complete for the committee the analysis of the replacement of the fighter aircraft, looking at interoperability, refuelling issues, runway length, and then, most importantly, the evolving threats that we face, both domestically and from foreign forces. Give us your insight on what the criteria should be for our next fighter aircraft.
