As per the newspaper article 3 of the 4 cabin crew on board were injured so that would just leave 1 crew to deal with 5 injuries. I very much doubt the 6 week training course includes how to deal with 5 different injuries at once, on your own, likely at different ends of the aircraft.
Fair play to whoever that crew member was, I think they deserve a lot more respect that some posters are giving them.
