While tragedy in the Antarctic seems to happen rather regularly, it is often more related to regular medical emergencies being a bigger deal due to remoteness or ship accidents. However, the most recent major news story out of the Antarctic is the Brazilian Comandante Ferraz base being damaged by a fire. The fire is reported to have destroyed much of the base.
The fire began in the engine room and the sailors attempted to put it out. Two died and one was injured. The rest of the personnel were evacuated to a Chilean base and a C-130 Hercules was sent to return them to Brazil.
