Co-pilot, stewardesses alive during crash

The exact cause of Sunday's crash is still unclear, although initial reports had suggested many on board were already dead or unconscious at the time of impact because of an apparent loss of oxygen and cabin pressure in freezing temperatures at 35,000 feet -- nearly 10 km up.

Giving results of autopsies on 26 victims, Philippos Koutsaftis told reporters: "All the (26) individuals, including the co-pilot and two stewardesses, died from multiple injuries to the body. They were alive when the plane crashed."

The Helios Airways Boeing 737 crashed into mountains near Athens, killing all 115 passengers and six crew on a flight from Larnaca to Prague with a stop in the Greek capital.
