Investigators struggling to work out why the Airbus 320 jet vanished from radar screens last Thursday, with 66 passengers and crew on board, are looking for clues in the human remains and debris recovered from the Mediterranean Sea so far.

The black box recorders, which could explain what brought down the Paris-Cairo flight as it entered Egyptian air space, have not been located.

An Egyptian forensic official said 23 bags of body parts have been collected since Sunday, the largest of them no bigger than the palm of a hand. The official, speaking on condition of anonymity, said their size suggested there had been an explosion although no trace of explosives had been detected.

But Hisham Abdelhamid, head of Egypt's forensics authority, dismissed this assessment as "mere assumptions".

French investigators say the plane sent a series of warnings indicating that smoke had been detected on board as well as other possible computer faults shortly before it disappeared.

The signals did not indicate what may have caused the smoke, and aviation experts say that neither deliberate sabotage nor a technical fault could be ruled out.

An Egyptian team formed by the Civil Aviation Ministry is conducting the technical investigation and three officials from France's BEA air accident investigation agency have also been in Cairo since Friday, with an expert from Airbus, to assist.

Egypt has deployed a robot submarine and France has sent a search ship to help hunt for the black boxes, but it is not clear whether either of them could detect signals emitted by the flight recorders, lying in waters possibly 3,000 meters deep.

The signal emitters have a battery life of 30 days.

Eighteen loads of debris have also been recovered, the Egyptian investigation committee said, in a search operation assisted by French and Greek aircraft. The U.S. Navy said Egypt had not formally requested American support beyond a P-3 Orion surveillance aircraft which was deployed on Thursday.

Last moments

Five days after the plane vanished off radar screens, Egyptian and Greek officials - who monitored the flight before it crossed into Egypt's air space - still gave differing accounts of its last moments.

In Greece, two officials stood by earlier statements that Greek radar picked up sharp swings in the jet's trajectory, 90 degrees left, then 360 degrees right as it plunged from a cruising altitude to 15,000 feet before vanishing.

But Ehab Mohieldin Azmi, head of Egypt's air navigation services, said Egyptian officials saw no sign of the plane swerving, and it had been visible at 37,000 feet until it disappeared.

"Of course, we tried to call it more than once and it did not respond," he told Reuters. "We asked the planes that were nearby to give it a relay and we could not reach it. That's it."

Cairo is seeking transcripts of calls between the pilot and Greek air traffic control, and wants Greek officials to be questioned over whether the pilot sent a distress signal.

The prosecutor also asked France for documents, audio and visual records on the plane during its stopover at Charles de Gaulle airport and until it left French airspace.
