Technicians at Antarctica scientific station killed
Two technicians working on a fire-suppression system at an Antarctica scientific station were found unconscious and died, the US National Science Foundation says.
The foundation says the two had been working in a building at McMurdo Station, which is on Ross Island.
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.
The pair was employed by a Virginia-based subcontractor and the deaths are under investigation.
