If they had known, it could have been possible. We did a lot of things. Like, when I flew, we had a lot of things in place to try to fix that one. We got rid of a lot of the foam that was unnecessary. We tried to do things that stopped the foam. We also had ways of detecting it so that we would know we had sensors and the wings. We added a maneuver we do when we fly up to the space station, we did like a pitchover where we took photographs of the, of the heat shield to see if anything got hit. So at least we would know and then we could, we could shelter in place on the space station. So there's a lot of things we could do with the shuttle, but the night, the thing about with dragon and Starliner and the new vehicles is they sit on top so there's no any foam that comes off the rocket is not going to hit you. So problem solved. So that, that's one example of how we don't have to worry about that anymore.
