SAO PAULO (AP) - Autopsies have revealed fractures in the legs,
hips and arms of Air France disaster victims, injuries that -
coupled with the large pieces of wreckage pulled from the Atlantic
- strongly suggest the plane broke up in the air, experts said
With more than 400 bits of debris recovered from the ocean's
surface, the top French investigator expressed optimism about
discovering what brought down Flight 447, but he also called the
conditions - far from land in very deep waters - "one of the worst
situations ever known in an accident investigation."
French investigators are beginning to form "an image that is
progressively less fuzzy," Paul-Louis Arslanian, who runs the
French air accident investigation agency BEA, told a news
conference outside Paris.
"We are in a situation that is a bit more favorable than the
first days," Arslanian said. "We can say there is a little less
uncertainty, so there is a little more optimism. ... (but) it is
premature for the time being to say what happened."
A spokesman for Brazilian medical examiners told The Associated
Press on Wednesday that fractures were found in autopsies on an
undisclosed number of the 50 bodies recovered so far. The official
spoke on condition he not be named due to department rules.
"Typically, if you see intact bodies and multiple fractures -
arm, leg, hip fractures - it's a good indicator of a midflight
break up," said Frank Ciacco, a former forensic expert at the U.S.
National Transportation Safety Board. "Especially if you're seeing
large pieces of aircraft as well."
The pattern of fractures was first reported Wednesday by
Brazil's O Estado de S. Paulo newspaper, which cited unnamed
investigators. The paper also reported that some victims were found
with little or no clothing, and had no signs of burns.
That lack of clothing could be significant, said Jack Casey, an
aviation safety consultant in Washington, D.C., who is a former
accident investigator. "In an in-air break up like we are
supposing here, the clothes are just torn away."
Casey also said multiple fractures are consistent with a midair
breakup of the plane, which was cruising at about 34,500 feet
(10,500 meters) when it went down.
"Getting ejected into that kind of windstream is like hitting a
brick wall - even if they stay in their seats, it is a crushing
effect," Casey said. "Most of them were long dead before they hit
the water would be my guess."
When a jet crashes into water mostly intact - such as the Egypt
Air plane that hit the Atlantic Ocean after taking off from New
York in 1999 - debris and bodies are generally broken into small
pieces, Ciacco said. "When you've had impact in the water, there
is a lot more fragmentation of the bodies. They hit the water with
a higher force."
Lack of burn evidence would not necessarily rule out an
explosion, said John Goglia, a former member of the U.S. National
Transportation Safety Board.
If something caused the lower fuselage to burn or explode,
"passengers would not be exposed to any blast damage" and the
plane would still disintegrate in flight," Goglia said. "These
are scenarios that cannot be ruled out."
Searchers from Brazil, France, the United States and other
countries are methodically scanning the surface and depths of the
Atlantic for signs of the Airbus A330 that crashed May 31 after
running into thunderstorms en route from Rio de Janeiro to Paris.
All 228 people aboard were killed.
Brazilian Air Force Col. Henry Munhoz said in a news conference
Wednesday that several body parts, as well as pieces of the plane
and luggage were found in the search area by the French amphibian
Munhoz did not provide further details, and Brazilian Capt.
Giucemar Tabosa Cardoso said "a significant" number of body parts
had been retrieved from the ocean.
Still missing are the plane's flight data and voice recorders,
thought to be deep under water.
French-chartered ships are trolling a search area with a radius
of 50 miles (80 kilometers), pulling U.S. Navy underwater listening
devices attached to 19,700 feet (6,000 meters) of cable. The black
boxes send out an electronic tapping sound that can be heard up to
1.25 miles (2 kilometers) away, but these locator beacons will
begin to fade after just two more weeks.
U.S. Air Force Col. Willie Berges, commander of the American
military forces supporting the search, said the black boxes emit
beacons at a unique frequency, virtually guaranteeing that any
signal detected would be from the pingers.
"The question becomes if the black box is with the pinger,
because they can get separated," Berges said. "If a signal is
located, the French would then send down a robotic vehicle that is
in the area to look at it, confirm that it is the black box and
bring it up."
Without the black boxes to help explain what went wrong, the
investigation has focused on a flurry of automated messages sent by
the plane minutes before it lost contact; one suggests external
speed sensors had iced over, destabilizing the plane's control
Arslanian said most of the messages appear to be "linked to
this loss of validity of speed information." He said when the
speed information became "incoherent" it affected other systems
on the plane that relied on that speed data. But he stressed that
not all the automated messages were related to the speed sensors.
The automated messages were not alarm calls and no distress call
was picked up from the plane, he said.
Air France has replaced the sensors, called Pitot tubes, on all
its A330 and A340 aircraft, under pressure from pilots who feared a
link to the accident.
Arslanian said a French doctor from the BEA was not allowed to
participate in autopsies done so far on some Flight 447 bodies by
Brazilian authorities, and those autopsy results have not been
released to the BEA. He said he was "not happy" with this
However, he added that French judicial authorities, who are
conducting a parallel criminal probe, were present at the
Brazil's Federal Police and state medical authorities in Recife
who are overseeing the autopsies said in a statement that two
French investigators, a dental expert and a doctor, had been
following the examinations as observers since June 10.
The French are leading the crash investigation, while the
Brazilians are leading the rescue operation.
