Of course, those in the UK know about Muckle Flugga, but to me it was..... um, interesting.
This lighthouse must be an Orbx only scenery because it doesn't exist in FSX.
This is Muckle Flugga in the Shetland Islands from P3d V3 (I didn't check the time of day nor the season)

And this is Muckle Flugga from P3d V4 (Notice how round the tower is?)

In any event, I'll be happy to never go out there in real life.
