I was on short finals in to Ronaldsway last year when I noticed 2 sea kings hovering over the runway about 200m from the piano keys. I was then utterly surpirsed when I was cleared to land, and even more gob smacked when I told them I was carrying out a missed approach and then told not to. After carrying out my missed approach and explaing why, it became apparent that ATC did not realise the Sea Kings where on the runway.
You gotta watch the olive drap helicopters!!!
