While the passenger may have misunderstood the directions/reasons ,where in the universe do people literally drag someone out like that? Ah yes, on an airplane! Remind me never to fly United. If I were him(passenger) I would sue everyone involved, to the max. The mere fact that he hit his head and they continued to drag him out instead of attending to his injury speaks VOLUMES. For heaven’s sake he is 69 years old this is the way they treat a paying passenger and an older man? I’d say us women better watch it, they might throw us over their shoulders after pulling us down the aisle by our hair and using a club on us.
