I would like to think that he would have led the way in blocking the aisle by just lying down and linking arms with others.
I would also like to think the would have sought to engage the security cops (who were obviously utterly untrained for this situation) and the other airline employees.
I also suspect that he would have acknowledged to them that they, the employees, were under huge pressure to get things done to unreasonably tight timelines. Indeed, maybe he might have suggested that the cabin crew and passengers were both victims, and that to see each other as adversaries is the wrong way to go.
Maybe the video would not have been so dramatic, but maybe it would have helped foster a much more powerful dialog about avoiding being divided, but rather uniting (so to speak.)
In any event, I hope many who fly are asking themselves what they would have done if they had been on the flight. I suspect that next time round, things will play out very differently.
