Maintenance is relatively low. Typically you're looking at using diesel engines, which are low maintenance. The airframe is obviously not an issue. You do have to have an inspection. Those ten days you're spending in the hangar include seven days for an annual end-to-end inspection. It has to have it annually.
The regulations for airplanes, which may be the same for the airships, say that every thousand hours, or whatever that number is, you have to go in for a check-over. There are certain checks that go along with that, and the regulations follow that, except, again, in Canada. Since we have no experience, and we have no airships, we really have no regulations like that.
In fact, this may be an opportunity for us. I don't suggest that we simply carbon copy what's been done in other places. We should look and see what's reasonable for Canada to do, because these are not the same as airplanes.
These are different vehicles. They don't fall out of the sky when the engines quit. They float around. You can come down to earth safely by releasing the emergency valves. They don't have the same kinds of pilot requirements in the sense that it's kind of a boring job, being an airship pilot, because you move pretty slowly. You're going along. It's not very exciting, as it would be in an airplane.
The regulations need to be developed specifically for this technology and not just carbon copied from someplace else.
To give you an example, again, my view is that with $100 million, you could buy three airships, the 20-tonne size, and have a hangar. That's enough to get started. That's a relatively low number compared to what it would cost to start up an airplane operation of a similar size.
