Well, I remodeled the former surface in a new way. This time I limited the area for the boundry tool and did a rail op. on the part of the fuselage that was going to be pretty smooth. Using the boundry tool on a limited way, makes the problem of surface irregularities smaller... um well, anyway... This is the finished part. I wish I knew more about modeling with nurbs patches, but do not have the patience to try to make this part better until I know more about nurbs-patching. Next I'll have to deal with the front part, which will be the second-hardest part in the project. And soon I'll be onto the fun parts... the details...
