The ATSB report include significant safety Issues involved in the failure of the computer algorithms that lead to the upset, although in the animation the situation doesn't look that bad, it certainly must be a good shake and not a good feeling for the flight crew.

What am I missing about this? How did the movement indicated in the animation lead to 119 injuries, 39 trips to hospital and 12 serious injuries? There's been actual crashes that have come out with less injuries.
On May 3, 2000, the FAA issued airworthiness directive 2000-07-27, addressing dual critical failures during flight, attributed to power supply issues affecting early Honeywell HG2030 and HG2050 ADIRU ring laser gyros used on several Boeing 737, 757, Airbus A319, A320, A321, A330, and A340 models
So there is no reason to make this thread A vs B or H vs N

Quoting AirbusA370 (Reply 1): What am I missing about this? How did the movement indicated in the animation lead to 119 injuries, 39 trips to hospital and 12 serious injuries?
Quite a good ABC report here that answers that question, AirbusA370. Basically the aeroplane was in 'normal flight,' the cabin crew were doing their jobs (i.e. not strapped in), and a lot of passengers didn't have their seatbelts fastened either:-
"Three minutes after the first incident, the plane pitched down again and dropped 400 feet.
"It caused a number of passengers, who were not wearing seatbelts, to hit the plane's ceiling.
"Out of the 303 passengers on board, 110 were injured, along with nine of the 12 crew.
"Twelve people were seriously injured and another 39 were taken to hospital."

Initially there is a positive G immediatly followed by the negitive G as the airplane's pitch attitude rapidly changes. Anything not secured, including passengers, carts, baggage, etc. fly through the cabin, and could even hit secured objects and people belted into their seats.
