After landing a very basic spaceplane on grass or other areas, it never slows down below ~10 m/s and literally just glides along like there's no friction or something even if the plane is literally sliding sideways. I've tried shutting down the engines and intakes. One time, I was on grass between two hills and it would literally just keep going back and forth between the two hills like it was a skatepark haha. I've recreated planes multiple times and this always seems to happen. I just want to be able to fly a plane, land, and then EVA, but can't get the plane to stop. Thanks.
