 you know, net zero emissions, things like that. And I know new data out here this week from the Engine Technology Forum, something we're going to take a look at right now. We're going to kind of keep this discussion going here today on AOA. Joining us now for a conversation, he is the Executive Director of the Engine Technology Forum, Alan Schaefer. We welcome him back to the program. Alan, it's good to talk with you again. How are you?
