I've been thinking for a while that I'm not sure, in the event, that I could have sorted who was the good guy and who was the bad guy in the short time available - e.g., on what side of the door he was on - e.g., whether to trust the four bars beating on the door, or to tackle them. Especially if I started to become aware when he was beating on the door and yelling. It would have been clear soon enough? I dunno. And if there was an ax involved? And if there were different conclusions by different passengers? Also, not sure what this says about some of the suggestions heretofore re the door and other last ditch security measures as we think about "the next time".
