The foundation said Wednesday the two had been working in a building at McMurdo Station, which is on Ross Island. It says they were found on the floor by a helicopter pilot who had landed after spotting what appeared to be smoke from the building.
Both were taken from the building and given CPR. One died at the scene. The other was flown to a clinic and pronounced dead shortly after. It happened Tuesday Eastern time.
