From what I read, it was the ground crew that screwed up and loaded the wrong amount in, and since the "fuel gauge" computer wasn't working, the pilot didn't know.
All in all, he managed to get safely get a 767 down with no thrust and only the ram air turbine generator providing power. From what I've read about the incident, he should not have been able to get the big airliner to glide nearly as far as he did. He obviously departed the recognized "recommended flight envelope" in order to do this. An Airbus product would have (assuming the control system was still getting power, ha ha) followed the max glide slope programmed into it and crashed since there is no override.
Makes me wonder what might have happened if United 232 in Sioux City had been a comparable Airbus instead of a DC-10. Of course, I don't know that a catastrophic engine failure would have led to a similar loss of hydraulics.
