Yeah. So that is something that's also not really a worry anymore. The reason that Columbia took that damage was it was foam. Like the big orange tank that's behind the space shuttle. It sticks up above the space shuttle, and some foam fell off of it. We always had some foam shedding off the thing, and in the beginning, we took that very, very seriously as a major problem. But the thing is, there's this concept of. I'm gonna forget the name of it now. Well, let me just describe it. So, you get away with something for so long that it's normalization of deviance. That's what it's called. So it's when you get away with something for so long, that something that was a deviant thing or something that was bad is treated as a normal thing. And that's what happened to us, because we knew that that foam coming off could do damage to the space shuttle. And in the beginning, we tried really hard to do something about it, and we treated it very seriously, but it was hard. We couldn't really come up with an easy fix. In the meantime, we're flying, and nothing bad was happening. What was really happening is we were getting lucky. And then eventually, a big piece came off, hit Columbia right in the wing, and it shattered. Made a big hole inside the wing, but nobody knew for sure. And they made a bad decision to not, like, investigate it further, assumed it was okay, brought him home, and obviously, you know what happened.
