Computer failure in this case = systems switched off (automatic) as designed. Crew flying manual to keep ahead of the problem. Final result = professional crew handled the situation and landed at the next available airport just in case there were serious injuries. The only big deal is what the press is making of it!!!!!
And of course those injured are now released from hospital as they only had "soft tissue" injuries (bruises). And if they had kept their seat belts on they too would not have suffered any injury. Among those treated were two crew members who did not enjoy the luxury of keeping their seat belts on while providing cabin service.
