Well, I think that the airlines know that they have to do something. And so it's a question of how do they do it, what do they do it, and what are the real terms? And that is, what are the real terms of contracts that lead to financeable debt deals? That's going to be the critical issue that has to get resolved. And we're working through partners on the customer side and the DOE on that issue. And everybody's cooperative. I think that everybody recognizes that we've run into, they've all seen this McKinsey work, they've seen the competitive analysis, we're very transparent about this stuff. And they see that the ATJ is the most cost competitive route to make SAF and to do carbon abatement. And an important point is this, I keep saying carbon abatement, this isn't about the actual cost to reduce the carbon. And so we're at about $450 per ton or so is what we would pencil out to be today. And the next best alternative half hour would be about $600 to $700 a ton. Power to liquids, which everyone is so enamored with, it seems, for capturing CO2 and making liquids that might be $1,100 to $1,500 a ton. So we're a fraction of the cost of some of those technologies. That data is sinking into people. And so ATJ is a fundamentally long run competitive product and technology. So it's about sorting that out. So at that SAF conference, a lot of discussion was about the various technologies and the cost of carbon abatement, what's real and what isn't. And then there is a question of financiers where they say, they hear so much noise about all these different technologies, it's confusing for them. They have no idea because everyone says, I have the new answer. And it's the greatest thing, it'll be free and things like that. Hi, we can use three pounds of hydrogen to make a gallon of jet fuel like you would with power liquids. Oh, and it'll be free, it's stuff like that. And so it doesn't, it isn't, that isn't real. So I think the reality of things are setting in for people. And of course, we come along and we're like, hey, this is the real deal, let's go. So we've got good partners that are being cooperative.
