What would be interesting to know about this flight would be the layout of the field, location of the heli-decks and the existing wind data. Having that information.....think through what the crew might have been seeing as they made their rounds in the field.
I can remember many a night shuttling in the Ninian Field in the lovely weather that exists there and having to make the takeoffs on instruments, get turned around towards the next stop and having to use radar to find the next rig/platform....even if just a mile or two apart from each other. That was back in the good ol' days of Decca which was not much help shuttling (or in cruise either). Depending upon the wind....it could be an easy trip over to the next deck upwind of your takeoff point and the other deck was in sight the whole time. With the wind from a different direction one would have to depart into the black void and get turned around to travel down wind to the other rig then get turned back into the wind for the landing which was more more work.
