That's an excellent question. I could give dozens of examples of how we have existing redundancies and how we could build more redundancies into our system. Let me give you just a simple example.
In the case of the reliance on GPS, as I have mentioned, Canada and the United States are removing a lot of our ground-based air navigation systems, because GPS is just as good and cheaper. Pilots are accustomed to using GPS for all kinds of operations. The problem is that, if GPS is off-line, if it's not accurate because of a solar storm or if jamming is occurring and it's a low-visibility day at Toronto Pearson airport, the pilots are then 100% reliant on ground-based systems for their approaches. If you were to take out that ground-based system, then the pilots would effectively be blind in low-visibility situations.
Now, no one is proposing to take the ground-based system out of Toronto Pearson airport, but we are taking ground-based systems out of a lot of smaller airports across Canada and the United States. On a normal day, 364 days a year, that's absolutely fine, but on that one day when the GPS is not functioning properly, perhaps because of a solar storm, the pilots are then in a more difficult situation. We want maximum safety with regard to essential functions like transportation. You keep the ground-based systems. You provide the redundancy.
It's the same thing with fibre optic cables. Just because we're reliant on satellites and they're absolutely fantastic, we shouldn't cancel our plans to build a fibre optic cable to Iqaluit. We should have redundant systems as much as possible.
Space is great, but if you get too reliant on one domain and you lose it for whatever reason, then you're in a real pickle. Wise policy-making is always looking to ensure backups. That's all I'm asking for here.
