 You know what it gets down to? I think you'll agree with us. It's not how much it costs, it's how much it's worth. Because look at SAF, sustainable aviation fuel. We already know it works. We already know what it cuts down. You can measure it and you can manage it. The problem is it's not being made in enough volume right now to be affordable. It's sort of like, you know, my parents got the first color television set, you know, like 1958, 59. It was unaffordable.
