The chief Athens coroner today said toxicological tests on the remains of the co-pilot, three flight attendants and two passengers from the crashed Cypriot jetliner showed they were not rendered unconscious by breathing carbon monoxide.

THE co-pilot and a flight attendant were among dozens of people still alive when a Cypriot airliner plunged into the mountains north of Athens, deepening the mystery over what incapacitated the flight carrying 121 people.

The Cypriot airliner that crashed in Greece may have suffered a sudden loss of cabin pressure at high altitude, causing temperatures and oxygen levels to plummet and leaving everyone aboard suffocating and freezing to death, experts said yesterday.

POLICE in Cyprus raided the offices of Helios Airways in the city of Larnaca yesterday, a day after one of the company’s passenger jets slammed into a mountainside near Athens, killing all 121 people on board.
