Debris found in Atlantic is NOT from Air France jet say red-faced investigators
By Peter Allen and Mail Foreign Service

The investigation into downed Air France flight 447 was thrown into chaos today when red-faced investigators admitted that debris found floating in the ocean was not from the doomed jet.
Military investigators had said that they had 'without a doubt' found vital parts of the Airbus A330 in deep ocean 600 miles off the coast of Brazil.
Among the debris was a wooden pallet that they believed had been used to load luggage on to the plane, which disappeared over the Atlantic early Monday morning with 228 people on board.
But today investigators said the wooden pallet and two buoys recovered was not from Flight 447, but just floating waste believed to be from a ship.
Earlier, investigators had also claimed to have spotted a plane seat and a seven-metre piece of fuselage floating in the ocean from search planes thousands of feet up.
They have not yet confirmed if those pieces of debris were from Flight 447 or not.
Brigadier Ramon Cardoso, director of Brazilian air traffic control, said: 'We confirm that the pallet found is not part of the debris of the plane. It's a pallet that was in the area, but considered more to be trash,' he said.
He added the Airbus that vanished on Monday did not have any wooden pallets on board.
'That's how we can confirm that the pallet isn't part of the remains of the aircraft,' Cardoso said.
Cardoso said the fuel slicks detected in the area were ‘almost certainly from another passing vessel too.’
Yesterday Brazilian Defence Minister Nelson Jobim rubbished the idea that the plane had been blown out of the sky by a bomb, saying that if an explosion had occurred on board all the fuel would have burned away.
‘If we have oil stains, it means it wasn’t burned,’ he said.
However with investigators admitting the fuel found floating in the water was not from the plane, speculation that the plane had fallen victim to a terrorist attack was growing again.
French investigators said no cause, including a terrorist bomb, had yet been ruled out.
And the French rounded on Brazilian investigators, with transportation minister Dominique Bussereau saying he 'regretted' the announcement that debris from the plane had been found.
'French authorities have been saying for several days that we have to be extremely prudent,' Bussereau told France's RTL radio. 'Our planes and naval ships have seen nothing.'
He said it is 'bad news' that the Brazilian teams were mistaken. 'We would have preferred that it (the debris) had come from the plane and that we had some information,' he said.
Three more Brazilian boats and a French ship equipped with small submarines are expected to arrive in the area in the next few days.
Cardoso said the search effort would continue, with the main focus on finding bodies, but bad weather is forecast for the region.
He said ships searching the area have not yet recovered any plane debris from the sea.
Debris spotted about 340 miles (550 kilometres) northeast of Brazil's northern Fernando de Noronha islands by the helicopter crew so far includes a 23-foot (seven-metre) chunk of plane, an airline seat, an oil slick and several large brown and yellow pieces that Cardoso said probably came from inside the plane.
French military spokesman Christophe Prazuck said the priority was looking for wreckage from the plane, before turning the search to flight data recorders.
'The clock is ticking on finding debris before they spread out and before they sink or disappear,’ said Mr Prazuck.
Air France officials have said the recorders, which could be deep under water, may never be found.
They have also warned that they are far from working out the cause of the crash.
Investigators are relying on a stream of up to six automated messages sent out just before the crash, which suggested the plane’s systems shut down as it flew through high thunderstorms.
The messages were sent out over a period of 14 minutes - indicating that pilots battled for nearly a quarter of an hour to save the lives of those on board.
The plane's navigational systems went into meltdown over the last four minutes, however, and pilots were unable to recover control of the jet.
The computer messages have suggested that speed sensors failed or iced over, causing erroneous data to be fed to on board computers.
This might have caused the plane to fly too fast or too slowly through the storm, leading it either to break apart or stall and fall out of the sky.
Pilot error was feared also. One of the automatic messages showed that the auto-pilot on board had been switched off, meaning the pilot had taken manual control of the plane, possibly in an effort to bring it safely through thunderous turbulence.
But yesterday there was speculation the pilot or co-pilots had slowed the plane too much, causing it to stall at 35,000ft, an event that could have been catastrophic.
Airbus has issued new advice to all airlines using A330s about optimal speeds during stormy weather after investigators suggested the plane may have stalled mid-air.
A high-altitude stall at 35,000ft would explain why the aircraft apparently broke up during appalling weather conditions.
Meteorologists said the jet entered an unusual storm with 100 mph updrafts that acted as a vacuum, sucking water up from the ocean.
The incredibly moist air rushed up to the plane's high altitude, where it quickly froze in minus-40 degree temperatures.
The updrafts also would have created dangerous turbulence.
Airbus declined to comment but retired pilot Jean Serrat said: ‘If accident investigators are making a recommendation so early, it is because they know very well what happened.
'The first thing you do when you fly into turbulence is to reduce speed to counter its effects. If you reduce speed too much you stall.’
A stall, in which the wings lose lift, would have made the aircraft uncontrollable.
Air France Flight 447 was en route from Rio de Janeiro to Paris when it plunged into the Atlantic four hours into its flight on Monday. All 228 people on board, including five Britons, died.
A Spanish pilot yesterday reported a flash of light at the time it disappeared. ‘Suddenly we saw in the distance a strong, intense flash of white light that took a downward, vertical trajectory and disappeared in six seconds,’ the pilot of an Air Comet flight from Lima to Madrid told his company.
Aviation trade publications focused on warnings in recent months issued by U.S. and European regulators about electronic systems on A330s and A340s that could throw planes into sharp dives.
Grieving families may sue Air France for ten of millions of pounds in compensation.
Mariana Paes, a friend of one of those who died, said: ‘People who lost want an explanation and full recompense for their loss.’
14-minute countdown to disasterAt 11pm on Sunday, the Airbus 330 was flying through black thunderstorms towering up 50,000 feet above sea-level, as updraft winds battered it at up to 100mph.
14 minutes later, with its systems failing, the plane was breaking apart and plummeting into the Atlantic ocean with 228 people onboard.
Exactly what happened during those terrifying moments may never be known, but the last messages sent out by the aircraft may give clues
According to the New York Post:
At 11pm (2am GMT) pilot Marc Dubois sent a manual signal saying he was flying through an area of 'CBs' - black, electrically charged cumulonimbus clouds that carry violent winds and lightning.
At 11.10pm, automatic messages relayed by the jetliner indicated the autopilot had disengaged.
This suggested Dubois and his two co-pilots were trying to thread their way through the storm manually.
At this point a key computer system had switched to alternative power and controls needed to keep the plane stable had been damaged.
An alarm also sounded, indicating that the 'fly-by-wire' system on the Airbus that controls the flaps on the wings had shifted to 'alternate law'.
Alternate law is an emergency back-up system that kicks in after an electronic failure. It enables the plane to keep functioning with less energy - but reduces stability, which would have been desperately needed as the pilots battled to bring the jet safely out of the turbulence.
At 11.12pm, two key computers monitoring air speed, altitude and direction failed. These would have increased the pilot's loss of control over the plane.
The loss of instruments showing air speed in particular would have been detrimental. The pilot was trying to fly a fine line between slowing the plane enough to navigate through the turbulence, and not slowing so much that the plane stalled mid-air, which would have been catastrophic.
The messages show there was an inconsistency between the different measured airspeeds shortly after the plane entered the storm zone.
At 11.13pm, control of the main flight computer, back up system and wing spoilers also failed.
The last automatic message, at 11.14pm, indicated complete electrical failure and a massive loss of cabin pressure - catastrophic events, indicating that the plane was breaking apart and plunging toward the ocean.
Last night Airbus warned airline crews to follow standard procedures if they suspect speed indicators are faulty.
The Airbus telex was sent to customers of its A330s late yesterday. An industry official said such warnings are only sent if accident investigators have established facts that they consider important enough to pass on immediately to airlines.
The recommendation was authorised by the French air accident investigation agency (BEA) looking into the disaster. It has said the speed levels registered by the slew of messages from the plane showed 'incoherence'.
Airbus said its message to clients did not imply that the doomed pilots did anything wrong or that a design fault was in any way responsible for the crash.
'This Aircraft Information Telex is an information document that in no way implicates any blame,' a spokesman said today.
