In the opening of the movie, Captain Robau (Faran Tahir) pilots a shuttle to the Romulan mining craft.
The shuttle he piloted has a set of plastic curtains between the pilot and the rest of the crew bay.
We see that other shuttles from the same generation (such as the medical evacuation shuttle that George Kirk's wife is evacuated on) and also shuttles from later generations (such as the one Pike uses to drop Kirk and the others from) have actual doors between the rear of the craft and the pilot.
What purpose would such curtains serve? Do they provide a film-element that I'm overlooking such as "indicates that it's a craft and not a set"?
Sidenote: is that canon I just missed and that's why they were used?
