So, when incomplete planes are transported from one factory to another, what does a plane look like before it is put together? Is it one whole wing, and fuselage with a hole for the wingbox, or an entire fuselage with wingbox and two wings?
Also, are wings attached to fuselage only once or repeatedly? That is, when a plane survives emergency landing somewhere where it is hard to take off again, does it have to be removed on ground in one piece, or can it be taken apart, be put back together again and return to flight?
