No, that's not true. #6 in her blog was absolutely incorrect. He was manhandled and drug down the aisle, hitting his head on one of the seats, and was virtually knocked unconscious to begin with. All of that was BEFORE he ran back on the plane, which I don't understand how that could have happened, that he was able to run back onto the plane. But his injuries definitely happened in the first go round.
There were several inaccuracies in her post, including that "must fly" business. The flight that the crew was supposed to man was due to leave the NEXT morning, and United could have gotten the crew there by driving 4 hours. As it was, the plane left three hours late, so driving would have gotten them there at almost the same time.
