Hi Pirandos,

You're starting out with a fairly difficult goal and there are more problems with the current model than just naked edges: little curve fragments, control point structure on tail surfaces that collapse down to a point rather than being a nice grid, a duplicate surface near the cockpit, and the center parting line isn't planar.

If I wanted to learn how to do this I'd go through the tutorials linked here:

And here's a tutorial specific to airplanes:

Overall I would try to make surfaces as large as possible and try to get them solid as soon as possible rather than hoping to stitch together a bunch of small surfaces at the very end. Solid operations like booleans are much nicer to deal with.
