Perhaps you can answer something:

In the movie, most of the English civilian boats are shown flying flags that are mostly red, with the Union Jack as a canton.

The one boat that is it's own story, picking up the shell-shock victim, the pilot, and the oil-covered survivors, flies a flag that is mostly blue with the Union Jack canton.

Is there a reason for this?
