Thank you, honourable member.
I don't think I'm qualified to speak to the costing of the relative systems. In Canada we don't use....
The Predator, for example, is a $22-million system. It is very cost-effective as compared with a combat aircraft. But it's not combat aircraft capable. They're not there yet.
The one thing I will say is that whether or not we buy the F-35, whatever fighter plane we do buy will probably be the last fighter plane we ever buy, because 30 years or 25 years later, when it's time to replace that fleet, it will be unmanned. I think there is really no question about that at all.
I don't think we're quite at the stage where UAVs can take over, but as I explained very quickly in the presentation, they can go into places that regular aircraft can't. They can loiter longer, and watch a target much longer than a regular pilot can. They're not ready to fight yet in the same way that a fighter plane is.
But I do appreciate it, sir.
