What went wrong with HELIOS flight?

GREEK air force pilots who were scrambled to investigate the doomed Helios Airways flight reported seeing the co-pilot "slumped over" the plane's controls.

Greek and Cypriot officials said communications were suddenly lost with the Helios Airways twin-engine Boeing 737 and two Greek air force F16 fighters scrambled to investigate.

The flyers "saw two people in the cockpit, we don't know if they were crew members or passengers, appearing to want to take over the controls," said Greek government spokesman Theodore Roussopoulos.

They saw "the co-pilot slumped over and perhaps unconscious and the pilot not in his seat," he said, adding that the oxygen masks were "activated" in the cabin. The Greek government spokesman confuted the arguments of a possible shotdown from the airforce.

"First indications from the Greek authorities are that this wasn't a terrorist attack," Cypriot presidential spokesman Marios Karoyan told journalists.

According to the Greek private TV station Alpha, a passenger sent a text message to a cousin saying: "We're cold, the pilot is blue. We're going to die. Farewell."

Water-dropping aircraft and helicopters were called to extinguish a fierce blaze that hampered the rescue operation.

The flight and cockpit voice recorders have been found, a Greek defence ministry official told.There is definitely a lot of mystery about the real reasons who lead to the crash.
