The AOC holder is mentioned by name. Or didn't you know they held an AOC?

It appears that the company quoted by the defence are not on the AOC holder's list on the CAA website dated Nov 2010, so no pax would have been on board. If no PT pax were carried, then it would be aerial work and presumably no AOC was needed.
Does this answer your question Whirls?
