Thank you, Chair.
I'd like to thank our guests for your testimony today. I find it very interesting. It is an area I'm not particularly familiar with, and I've certainly learned a lot today. I guess I have old impressions of what you've been discussing today. When you think of the ice roads up north, of course, then there's the television show. When you talk about airships, respectfully, I think of the Hindenburg, and that's probably not an example you'd want to bring up today. Then I think of the RE/MAX commercial Above the Crowd! with hot air balloons. Mine is a naive and stereotypical impression of the various aspects of the industry.
It's fascinating where you're going. Yours is an old technology that you're now trying to bring forward as a new technology in an interesting kind of way. I'm trying to understand the economics of it, because I heard you say there were 15 to 25 days of fog when De Beers couldn't work as a result. You've now indicated, I believe, Mr. Prentice, that an airship could work in fog.
