Early in the movie Prometheus, we see the ship traveling through space with wording being displayed on top of it.
As you can see, the crew count is displayed as 17.
During the briefing after the crew has been awakened at its destination, we see this collection minus the ship's captain and Vickers.
From my count, we seem to be a few members short of the aforementioned 17. It seems that at least 3 members may be missing from this group shot. Additionally, if we take David (an android) out, we are now at four members not displayed. So as I originally asked, does Ridley Scott tell us that there are more people on board, because in later events, we do find out differently?
