At least somebody might have managed to connect "Pilot" with a pilot jack.
Sadly the jack is flown from the front end (well, this is a River forum

) and then by the ship requesting such services.

So what about 5/10 for trying?

Some might say nobody including residents understand the British flag system, ensigns, who, when, where hoisted or struck, and jacks.

Time for a general rant about archaic nonsensical, etc, etc
