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.

Two black-box recorders from the Cypriot airliner that crashed outside Athens will be sent to France for expert examination, officials said today, to determine why the plane went down – possibly with all 121 on board already dead.

Greece’s worst plane crash, in which 121 people died yesterday, appeared to have been caused by a sudden drop in oxygen.

A Cypriot airliner ploughed into a hill north of Athens today, killing all 121 people on board, Greek officials said.
