It was known, but it wasn't known fully.
With everything in Canada, really, you have to wait, including train disasters, for example. Take the Lac-Mégantic derailment, which the Transportation Safety Board is obviously working on now. We won't know what really happened for maybe another year or two. It's the same with a lot of accidents like that.
Your second question, on the night flights, interests me. When I warned the C-NLOPB about night flights, we didn't have a dedicated search and rescue helicopter. We didn't have a 15- or 20-minute wheels-up time. We didn't have FLIR, or forward looking infrared radar. We didn't have in the aviation industry what pilots call the “goodies” that we now have, Therefore, I was very concerned about night flights.
One of the great helpers to me was DND. Now, I couldn't make any recommendations about DND, but DND took me on night training flights. They took me on day training flights. They even let me go down on the wire. These were good experiences that taught me. When you are over the ocean at night, the ocean is black, and the sky is pretty black too. You have night-vision goggles that help you. We have these things now. But we didn't have them when I was concerned about night flights and, therefore, I gave my warning.
I'm not going to second-guess what C-NLOPB will do. They're going to have to make a decision on this. The situation now is much more amenable, if you like, to night flights. I don't know what they'll do, but it's more amendable, because we have these.
We didn't have auto hover. We now have auto hover, which holds the helicopter in place. The pilots are right there to instantly take over if they have to, but the helicopter is under the control of the flight engineer. Using a toggle switch, he can move it laterally forward or backward, but not up or down.
We have all these things. That means night flights can be viewed in a different manner, whatever the decisions are.
Still, I agree with you that it's more dangerous to rescue at night, and perhaps more difficult. That is true. But at the same time, a risk assessment has to be made, because maybe the risk is acceptable. If you go to the North Sea, they fly at night there. But again, as we know, the search and rescue effort in the North Sea can never really be duplicated in Canada's offshore. They have them coming from Norway, Scotland, the U.K., and Denmark. It's a different thing. The ground has changed since I brought it to the attention of the C-NLOPB.
There's another thing, too. We are going, I believe, into the north. I think oil exploration and extraction are going to go into the north. If they do, there's going to have to be night flying, because there's not much daylight as you go north. They found this in northern Norway; there's hardly any daylight there, and they have to fly at night.
What I think could be a solution or what could help toward a solution is to not schedule night flights. If you schedule night flights, then the flight will go as long as it's fit to fly. A helicopter can fly at night just as easily as it can in the day. It's when search and rescue becomes necessary and important that the night poses difficulties. It not only poses difficulties for passengers who might go down and find themselves in the water, but also poses dangers and difficulties to the very brave people who set forth to rescue them.
