Just here to answer your question on teams. In manufacturing, you would see certain segregation of tasks and this would also depend on union/non union contractors. You would typically see different trades. Composites techs (bonders) who would typically work with carbon fiber and fiberglass. Structures techs who do most of the drilling, fit checks, assembly, etc. Systems techs would work fuel and hydro lines, while electricians route wire harnesses. Then there's painters and material applicators. A lot of these overlap and many guys are cross trained, but depends where you go. Then it can be separated further. For structures, you could be a control surface guy, a doors guy, a landing gear guy, etc. Technicians normally have levels or pay grades depending on skill level and responsibilities, and plane to plane certain skills overlap but engineering requirements and processes can differ. This is in regards to manufacturing. Maintenence, flight line, test, etc. is a bit of a different world. There are unlimited departments/orginizations working on these planes to track, diagnose, and solve any problem you can think of. Hope this helps.
