It sounds like the passengers were very calm and cooperative with each other, it's a good reminder that most people in general arent terrible most of the time. The people who were willing to unhook themselves and drop to the floor/upside down roof gathered together to help catch the others. This could have been bad if there were more babies or kids in laps, not to mention those with physical disabilities. At least it happened on a runway where the fire trucks were so close.
I hope their adrenaline comedowns weren't too severe.
