RWA just found what I found. Initially the report was the captain went to manual braking with 500 meters remaining. I flew into TGU a few days before they pulled it out of the ditch right before the cliff between the taxiway and runway. The pilot had skidded it around to the left about 150 degrees to keep it from going off the end. I can not find that report now but as RWA said, it was considered an incident, not an accident. Eye witnesses said they landed long. I have had reverser failures landing there and stopped with plenty of runway left. They did quite a bit of maintenance checking for engine FOD and replaced tires. That must have been quite a ride skidding backwards into the ditch probably using forward thrust to stop.
