Yes. Look, the short answer is, as we said in the remarks, we deploy capital and lock step with demand. You can well imagine because we're the market leader here and have been for a long time, both in simulators and simulator-based training, we know the market very well, and we know our customers very well, and we're in constant dialogue with them both in the airline sector and the business aviation sector. So, we have a pretty good and informed idea of how much demand will be required because remember, it's a regulated market. People – there's a – you can just look at how many flights people expect to make, how many deliveries are coming out of the OEMs, and you will be able to establish what is the demand requirement across the world approximately. So, that's how we deploy it. And we – in terms of what is the practical capacity, look, I'll tell you, I was our training center in Minneapolis about three weeks ago, where we are anchor customers are some of the largest regional carriers in the United States, like Endeavor, for example. And I can tell you, our training centers there are operating above 100%. And teams are doing a great job. So, when you talk about practical capacity, you can get up there and you can sustain it when you need too. And that's I believe you me to support the training of regional carriers in the United States right now, they need us to be operating at that level. So, we can do it. So, there's elasticity there now in practical reasons. When we define 100% for airlines, get you a little bit detailed here, but that's 6,000 hours a year, which is 16 hours a day. So, that's what we consider a practical limit. But again, we're doing higher than that. So, there's flat. If the demand is there, that's what we do. And when we get to those kind of levels, well, yes, what? In Minneapolis, there was a bunch of good nice tractor trailers or backhaul is building two new simulator base in Minneapolis, while I was there because clearly, demand is there. And we secure long-term contracts. We're not speculative on how we deploy that capital.
