 So Raider is rapid airfield damage repair. So basically we come out, we assess the hole, see how deep it is, how wide we need to cut. I'm going to clean out the holes, fill it up to a certain amount, and then we'll cap it with our volumetric mixer. Once it's set, after enough time we can run that plane over. From start to finish, it depends on how many graders we did with. Today we did three graders and it took us maybe about four hours to do all three full depth. But we really train for this a lot. We have an exercise almost every month. So it's always a good feeling because you always can look back and see it work. Who knows, I could be taking off out of here one day and I can look down and see the squares that we did. Just know that I'm the reason we're taking off right now.
