Also, I guess the model has isolated triangle faces around the wheels, partly wrongly inversed. (one may call this effect of excessive edge splitting :-) ) Repairing can be achieved using Meshlab or something similar; Wings3D cannot solve that issue.

Cleaning of model is necessary. Delete the old (broken) polygons. Merge new sections together. "Welding".

Ditto.
I had a look into the model myself, and I saw many of the problems stated by the_frog and by Wise
The sharp edges on the top of the fuselage are caused by isolated faces. Fixing the problem is a matter of welding them in MeshLab, or with any other program capable of advanced mesh manipulation. I use Mod Tool for that.
Sharp edges + dark triangles on the bottom of the fuselage near the landing gear, in the radiator, and in some of the canopy beams, is caused again by non-contiguous edges, and by those triangles being "twofold", i.e. being composed by two coincident faces welded together, each pointing to opposite directions. The cure is removing manually the faces with wrong normals, and welding the remaining triangles with each other.
Last, I see some redundant meshes, i.e. meshes which are entirely enclosed within the fuselage and cant be seen when the model is assembled. They don't do any harm, but they are consuming computer resources without a valid reason. Removing them is an easy task.
All in all, I think the model is the result of a quick conversion from a format not compatible with the Wavefront (obj) file format. Fixing it is possible, but it will require some tweaks and a general clean-up. If no one else is volunteering for that job, I will put it in my to-do list
