Fifteen people were killed and dozens of passengers were taken to hospitals after a plane crash landed and burst into flames in eastern Venezuela. 

“There are exactly 36 people who are, thanks to God, still among us and 15 people who died,” Bolivar state Governor Francisco Rangel Gomez said on state television this evening.
The accident occurred at 9:50 a.m. as the ATR-42 turboprop operated by state airline Conviasa was nearing its destination of Ciudad Guayana, 330 miles southeast of Caracas, after having taken off from Margarita Island. The pilot reported he was having problems controlling the turboprop before the crash, according to the regional disaster response chief, Jose Garcia.
A photograph published online by Globovison showed the charred remnants of the plane after it crashed near a steel mill owned by Siderurgica del Orinoco. The aircraft broke into pieces after coming down in an empty lot 6 miles from the airport.
Representatives of the French airplane manufacturer Avions de Transport Regional will visit the site to investigate the cause of the accident, Transport Minister Francisco Garces said. ATR is a joint venture of European Aeronautic, Defense & Space Co. and Finmeccanica SpA.
Rangel Gomez said one worker from the steel mill climbed into the plane shortly after it crashed and pulled out survivors. The worker was being treated for smoke inhalation, Rangel Gomez said.
Government officials had originally said that the airplane from flying to Margarita Island from Ciudad Guayana.
Venezuela’s last major aviation disaster was in February 2008, when an airplane belonging to Santa Barbara Airlines crashed in the Andes mountains near the city of Merida, killing all 46 people on board.

Asia Puts Its Stamp on Aviation Farnborough Airshow:- CNBC

Asia Puts Its Stamp on Aviation

The future of the aviation industry has an Asian face, industry watchers say – and it is changing fast thanks to the rapid growth in passengers in the region that is creating strong demand for aircraft.

“Some two-thirds of the total global aircraft orders are for aircraft in the Asia-Pacific and Middle-East regions,” Peter Harbison, the executive chairman of the Sydney-based Centre for Asia Pacific Aviation, said. “This promises to reshape the face of aviation in the next decade.”

In all, there are 2,226 planes on order for Asia and another 710 for the Middle East, according to the center, which tracks aviation trends. That’s out of a global total of 5,601, with 1,438 on order for Europe, just 798 for North America and only 429 for South America.

It is China that is at the forefront of the boom, consistently seeing double-digit growth in passenger numbers over the last five years. With Japan’s market stagnating and Japan Airlines even reducing its overall fleet, Chinese airlines now constitute around 40 percent of the aircraft orders in Asia.

Chinese airlines saw total traffic of 21.5 million passengers in May, up 18.2 percent over the same time a year ago. That’s an annualized rate of around a quarter of a billion passengers per year, 93 percent of them domestic.

“It is the domestic market that is really firing,” Harbison said, creating a lot of demand for narrow-body, short-haul planes. But as Chinese airlines expand internationally, that should driven demand for bigger long-haul aircraft.

In fact, the demand for wide-body aircraft is even more starkly weighted toward the East, with 1,211 of the 1,906 wide-body planes currently on order destined for Asia and the Middle East. Those are mainly planes such as the Boeing 787 and the Airbus A350 that will make more direct flights between smaller cities possible. Together with greater liberalization of access to airports in Asia, new travel hubs are likely to spring up in region.

“The shift in the balance of power in long-haul flying is the most obvious conclusion to be drawn from this,” Harbison said. “The airport hubs of the future will be developed in Asia.”

Still, the Chinese airlines are still some way from matching their U.S. counterparts in terms of size. In 2009, Delta Air Lines carried 161 million passengers worldwide, making it the largest airline in the world – although it is not the largest within the United States, where Southwest Airlines carries the most passengers.

By contrast, China Southern, the largest Chinese airline in terms of passenger volume, is around one-third of the size, carrying only 61 million passengers last year. But it is in rapid expansion mode, with 316 aircraft already in operation and 134 on order, a 42% increase. Delta, on the other hand, has 446 aircraft in operation but only 38 on order, or 9% of its fleet.

“This is where you see what the future is,” Harbison said. Delta also saw a decline of 10 million passengers last year, compared with the previous year, while China Southern’s tally grew by 3 million.

The trend holds true throughout the Chinese aviation industry. China Eastern, the second-largest carrier in the country, flew 44 million passengers last year, up 7 million over the year before. It has a fleet of 244 planes, and has 102 on order, a 42 percent boost.

Air China rounds out the triumvirate of major Chinese airlines. It carried 40 million passengers last year, an increase of 6 million, and is China’s main international operator. It currently operates 244 aircraft and has another 139 on order, a 57 percent increase.

Air China’s new planes will be roughly evenly split between Boeing and Airbus, with the largest orders on the assembly line for 37 Boeing 737s and 30 A320s. It’s the same case for China Southern, with a balance between the Boeing and Airbus, and large orders for the 737 and A320. Although China Eastern’s orders are skewed toward the 320, with 62 on order, the lack of favoritism is not surprising. China still has a centralized ordering system for its airlines.

Its domestic airline construction industry is still nascent. But China, having cooperated with both Boeing and Airbus, is keen to put that knowledge to use in developing its own planes.

The Commercial Aircraft Corporate of China, or COMAC, is currently developing China’s first home-made jumbo jet, the C919. China Eastern, China Southern and Air China are all likely customers, with the first orders possible before the end of this year, according to the Beijing Daily.

Honeywell International, which has won a contract worth more than $1 billion to supply the flight-control system for the C919, says the aircraft is scheduled to enter service in 2016, with more than 2,000 to be built over the next decade.

China is building on a huge aeronautics industry, based around both military and commercial aircraft and parts. The Aviation Industry Corporation of China, the umbrella state-owned company, has more than 400,000 employees and 200 subsidiaries. So it’s no surprise Chinese companies will start to take on Boeing and Airbus. But it remains to be seen how long it takes before they establish themselves as significant competitors.
“I think everyone who is realistic realized it was going to happen sooner or later -- it’s just a question of when that will be,” Harbison said. “They’re targeting having the capability in the second half of this decade. But it’s a long time between having the capability and becoming a major market player.”

Netanyahu Security Officers' Guns Lost on U.S. Visit - WSJ.com

new toys for the security guards...



Israeli Guns Lost on U.S. Visit

Israeli Prime Minister Benjamin Netanyahu's security detail lost four high-powered semi-automatic guns over the weekend when its luggage was rerouted across the U.S., only to resurface without the weapons.
Members of the prime minister's security team flew on Israeli airline El Al Sunday into John F. Kennedy airport in New York, in advance of Mr. Netanyahu's visit with President Barack Obama, according to officials with knowledge of the incident. After passing through customs, the Israeli security officers checked two hard carrying cases—one containing four .40-caliber Glock handguns and the other containing three Glocks—before boarding an American Airlines flight to Washington, the officials said.

The officials said Transportation Security Administration agents made sure the security officers had permits for the weapons and affixed stickers to the cases indicating clearance for the guns and their transport. The TSA agents then forwarded the cases to American Airlines baggage handlers to be loaded onto the plane, according to the officials.

The security officers arrived in Washington Sunday evening, but the case with the four guns didn't, the officials said. American Airlines personnel found the case, with its Washington destination tag still on it, at a Los Angeles Airport terminal at around 4 p.m. on Tuesday in L.A., about two hours after Messrs. Obama and Netanyahu met at the White House to discuss U.S.-Israel relations.
The locked case—which wasn't checked by the American personnel who found it in L.A. to see if it still had the weapons—was put on an American flight to Chicago and then to Washington, the officials said. When the security officers opened the case, they discovered that the four Glocks were missing, the officials said.
Investigators with the Port Authority of New York & New Jersey police, the lead investigative agency in the incident, reviewed security videotape that confirmed the TSA agents processed the cases at JFK Airport and passed them on to baggage handlers working for American.
An official with knowledge of the incident said the investigation at this point is focused on employees of American and the baggage handlers it contracts.
American spokesman Tim Wagner declined to comment on what he called "a potential security incident." The TSA declined to comment, citing an ongoing investigation. Officials at the Israeli Embassy in Washington deferred comment to U.S. law-enforcement agencies investigating the incident and to American. A spokesman for the Port Authority police declined to comment.

Airline Security: Gentle Solutions to a Vexing Problem | STRATFOR

Airline Security: Gentle Solutions to a Vexing Problem


Central America: An Emerging Role in the Drug Trade
By Fred Burton and Ben West
U.S. President Barack Obama outlined a set of new policies Jan. 7 in response to the Dec. 25, 2009 Northwest Airlines bombing attempt, which came the closest to a successful attack on a U.S. flight since Richard Reid’s failed shoe-bombing in December 2001. As in the aftermath of that attempt, a flurry of accusations, excuses and policy prescriptions have emanated from Washington since Christmas Day concerning U.S. airline security. Whatever changes actually result from the most recent bombing attempt, they will likely be more successful at pacifying the public and politicians than preventing future attacks.
At the heart of President Obama’s policy outline were the following key tactics: pursue enhanced screening technology in the transportation sector, review the visa issuance and revocation process, enhance coordination among agencies for counterterrorism (CT) investigations and establish a process to prioritize such investigations. While such measures are certainly important, they will not go far enough, by themselves, to meaningfully address the aviation security challenges the United States still faces almost nine years after 9/11.

Holes in the System

For one thing, technology must not be seen as a panacea. It can be a very useful tool for finding explosive devices and weapons concealed on a person or in luggage, but it is predictable and reactive. In terms of aviation security, the federal government has consistently been fighting the last war and continues to do so. Certain practical and effective steps have been taken. Hardening the cockpit door, deploying air marshals and increasing crew and passenger awareness countered the airline hijacking threat after 9/11; requiring passengers to remove their shoes and scanning them prior to boarding followed Reid’s 2001 shoe-bombing attempt; and restrictions on liquids and gels followed the 2006 trans-Atlantic plot. Not enacting these measures would have meant not learning from past mistakes, and they do ensure that unsophisticated “copycat” attackers are not successful. But such measures — even those that are less technological — fail to take into account innovative militants, who are eager and able to exploit inevitable weaknesses in the process.

From Choppers with Buds

Few hurdles for Canada smugglers to get choppers

His case illustrates the remarkable ease with which smugglers have obtained flight training and helicopters as they grab a share of Canada's sprawling, multibillion-dollar trade in marijuana, cocaine and MDMA, or Ecstasy.

Of about 10 pilots arrested in roundups of British Columbia-based helicopter smuggling operations this decade, at least half had recently trained at flight schools, sometimes dropping out once they knew just enough to handle the machine, an Associated Press review found.

Flight school operators say they don't check a student's background or monitor what students do on their own time, though they generally do ask why a student wants to become a pilot. Several said they don't want to train smugglers, but they also don't want to turn away business simply because a prospective student might be heavily tattooed or pay in cash.

"I don't think there's anything we can do," said Chinook Helicopters owner Cathy Press, who has seen several former students arrested for smuggling. "If you went and thought everyone was drug-running, you could tell the police, but maybe you're wrong — and that's not great for business."

Even if her suspicions were correct, she added, "They might put someone in jail, but someone else will step forward, so why get in the middle of it?"

A clean criminal record is not a prerequisite for a pilot's license, said Rod Nelson, a spokesman for Transport Canada, the government agency that oversees the aviation industry. Nor do Canadian officials ask students to disclose previous convictions. They do ask about any substance abuse in an applicant's past.

The U.S. Federal Aviation Administration takes a similar approach, asking flight students to disclose previous convictions and requiring background checks only of foreign students, spokesman Paul Turk said.

Sam Lindsay-Brown was a clean-cut, friendly 23-year-old when he showed up at Chinook Helicopters in Abbotsford to begin flight training in December 2007. He was also a drug smuggler. And for almost a year after Canadian police began investigating him, he remained enrolled, essentially working his way through flight school as a co-pilot on cross-border drug flights.

U.S. agents arrested Lindsay-Brown in February as he put his training to use by making a 426-pound marijuana drop in northeastern Washington state with one of Martin's leased helicopters. He committed suicide in jail four days later.

The Royal Canadian Mounted Police and Transport Canada note that they can't bar people from studying as a pilot or obtaining a license without proof of criminal activity.

"The guy's 20-some-odd years of age, and he's gaining qualifications that can be used for a lawful purpose," said RCMP Cpl. Dan Moskaluk. "It's a tragedy that he chose to get involved in this line of business, instead of pursuing the lawful side of the skills he was acquiring."

The RCMP declined to say whether agents were aware he had been enrolled at flight school. They had been investigating him since spring 2008, after a woman he hired to transport 200,000 tabs of Ecstasy was arrested in California and gave his name to police.

RCMP spokesman Norm Massie said the agency had no record of Lindsay-Brown making prior smuggling flights, but two coconspirators confirmed to the AP that Lindsay-Brown had made several as a co-pilot, meaning he would be paid at least $5,000 to help load and unload contraband and keep an eye out for trouble.

The coconspirators spoke on the condition of anonymity because of their own involvement in criminal activity and fear that they could face repercussions from otherdrug traffickers for speaking with a reporter.

Massie declined to discuss what steps the RCMP takes to monitor flight schools, but said the agency knows that some traffickers get training there.

"We would be remiss not to include that in our investigative techniques," Massie said.

Martin, 37, was sentenced in 2007 in Canada to 2 1/2 years in prison for leading a major drug-smuggling operation in the 1990s, one that started using an airplane after ground couriers were caught.

He said he became involved in drug trafficking about 16 years ago and remains well connected in the smuggling world, though he declined to discuss specifics; he was arrested but has not been charged in Lindsay-Brown's case. In interviews with the AP, he estimated that as many as 30 pilots across Canada make drug-smuggling flights at least occasionally.

Someone looking to hire a pilot can put the word out via Blackberry and hear from pilots as far away as Quebec or Australia by the end of the day, Martin said.

In dozens of interviews with smugglers, pilots, lawyers, Canadian and U.S. authorities, and operators of flight schools and helicopter companies, a snapshot of the highly specialized profession emerged.

Some drug-running pilots are highly experienced. Some do it full-time, and some do it on the side when legitimate business gets slow or unexpected expenses such as helicopter damage leave them struggling to pay the bills. Some enjoy the rush. Some have a thing for getting America high. They all like the money.

One, Shane Menzel, told a federal judge in Seattle that he turned to smuggling because it was so hard to find work as an inexperienced pilot. Many "low-time" pilots must work for years washing helicopters and cleaning out hangars before they get a real flying job.

People familiar with British Columbia's marijuana trade have estimated that anywhere from 30,000 to more than 80,000 pounds of pot per month is smuggled into the United States.

It's a huge business, infusing billions of dollars a year into the province's economy. The province's most prominent gangs — the Hells Angels, the United Nations, the Independent Soldiers — are believed to own most of the drugs moved across the border, but to avoid heat they leave the shipping to others.

Air transport is generally considered the best way to exploit the vast, unpopulated terrain along the border.

Planes can fly faster and farther than helicopters, but need airstrips. Helicopters can skim treetops — flying as close as three feet — to avoid radar detection. They can dart through low mountain passes or river valleys and land at a remote clearing or even a wide spot in a logging road, where they're met by GPS-equipped drivers. They're back across the Canadian border in minutes.

Often, no cash crosses the border, because it might be seized or difficult to exchange, Martin said.

Instead, whoever moves the marijuana or Ecstasy south gives the profit to a U.S.-based cocaine trafficker. That trafficker instructs a contact north of the border to pay the Canada-based owner of the marijuana or Ecstasy.

The cocaine trafficker then takes the proceeds from the marijuana to buy cocaine to be shipped north into Canada, where the transaction happens again in reverse.

A helicopter smuggling operation charges about $350-$550 per pound to fly marijuana south of the border, and $1,500-$1,800 per kilogram to bring cocaine back.

Such an operation, of course, needs helicopters. In Canada, it is difficult to lease a helicopter without an operating certificate, a Transport Canada document that allows someone to use a helicopter for commercial purposes. Such a document is a sign of legitimacy to leasing companies, who typically want to know what their machines are being used for.

But there are ways around that hurdle.

Many smugglers instead simply buy helicopters, registering them to "numbered" companies — 123456789 Ltd., for example. There are 90 helicopters registered for private use to such companies across Canada, Transport Canada records show.

In other cases, smugglers have paid third parties to register the machines for them, or they're not registered at all. One unregistered helicopter with the tail mark C-FTCH has been used in smuggling runs and recently was parked deep in the woods near Cranbrook, in the mountains of southeastern British Columbia, three people with knowledge of the machine told the AP.

Martin bought the first helicopter he acquired in 2007, sight-unseen, for $925,000 from an owner in Texas. No conditions of his bail prohibited him from possessing aircraft. Massie declined to discuss Martin's case, but said generally: "Should those conditions be in place? Absolutely."

The helicopter was eventually repossessed when he couldn't afford more than $1 million in repairs. Meanwhile, Martin tried to lease another helicopter through Gorge Timber, a company registered in his wife's name. The helicopter was a Eurocopter EC-120 put up for lease by a British Columbia company called Vertical Solutions, run by Kevin McCart. Martin said he didn't think he'd be able to get the lease without an operating certificate, but a Calgary city police aircraft engineer, Greg Solar, who had helped him repair his first chopper, had a connection.

"I thought, 'We're a little company, we don't have the best books,'" Martin said. "And all of a sudden Greg's saying, 'I know Kevin McCart. I'll put in a good word for you guys.'"

Solar and McCart declined to speak with the AP, but Martin said he leased the EC-120 for $30,000 U.S. a month, including insurance and maintenance. He had it for about nine months, until last fall, when the owner took it back because uninsured pilots had been flying it. The helicopter was used in cross-border drug flights, Lindsay-Brown's coconspirators told the AP.

Early this year, Martin used Gorge to lease another machine — the Bell 206 Jet Ranger that Lindsay-Brown was arrested in — from Eagle Copters of Calgary, one ofCanada's most prominent helicopter companies.

Mike O'Reilly, Eagle's president, did not return repeated calls from the AP.

"Sure, I have a past, but those charges were a decade ago," Martin said. "If you have the money and you want to get into a helicopter business, you can — doesn't matter who that individual is."

On Feb. 23, the day of his arrest, Lindsay-Brown climbed into the Jet Ranger at Martin's shop and flew it to a snowy clearing outside Ione, Wash. He was to drop off 426 pounds of marijuana and pick up 83 kilos of cocaine, authorities said.

But the driver he was meeting, Len Ferris, had been arrested in Utah with the cocaine. For more than a day, Ferris did not return Blackberry messages from Sean Doak, a recently paroled drug trafficker who was his contact on the Canadian side of the border, Martin said he later learned from Adam Serrano, another man arrested in the case.

That was a clear sign of trouble, but Doak never told Lindsay-Brown about it, and Lindsay-Brown had no clue he was flying into a setup, Martin said.

U.S. agents greeted him with guns drawn.

Martin reported the helicopter stolen. The DEA said it didn't believe him and returned the machine to Eagle Copters.

The following week, another pilot flew down to meet Ferris — with predictable results. This time, it was Jeremy Snow, who recently had done flight training at Okanagan Mountain Helicopters in Kelowna. He was arrested as he landed in Idaho, pleaded guilty in U.S. District Court in Seattle and is expected to face four years in prison.

The computer crash - Air France 447

Air France 447: The computer crash

As the first bodies from Air France 447 are found, investigators suspect a terrifying mix of weather and technological weakness was responsible

Airbus A330-200

Airbus A330-200 similar to the Air France plane which vanished from radar after leaving Rio de Janeiro in Brazil on route to Paris.

When things go wrong at high altitude, one of the deadliest challenges for pilots is a phenomenon known as “coffin corner”. This is the point, tens of thousands of feet up, where the margin for error in controlling a sophisticated modern airliner becomes tiny. Investigators are now wondering whether Air France flight 447, which disappeared last week with 228 people on board, may have flown into coffin corner never to escape.

For amid all the speculation and mystery, two events are clear in the worst aviation disaster for half a decade. At 3am BST last Monday morning flight 447, a four-year-old Airbus A330-200, reported that it had encountered “stormy weather with strong turbulence”. Ten minutes later, the plane’s autopilot disengaged, according to its automatic communications and reporting system (Acars).

Somewhere around 35,000ft, with storm winds raging and the plane buffeted on all sides, the crew found themselves trying to fly 230 tons of electronic wizardry by hand. At that altitude, it is far harder than passengers imagine.

Whoever was in the pilot’s seat was looking at two computer screens, a host of other instruments and two rudder pedals – but no traditional hand controls. Instead, an A330 pilot reaches for a small joy-stick to one side. It looks a bit like the control for a games console. Through that “sidestick”, the pilot flies the plane with electronic signals, rather than any mechanical linkages.

“It’s tricky. At altitude big planes wallow about,” said Roger Guiver, a former British Airways pilot. “It’s like trying to steer the QE2 with a 2ft rudder.” Jean-Pierre Albran, a former French air force pilot, said: “On a [Boeing] 747, you feel things with your hands. On an Airbus, you’re just looking at screens.”

On a British web forum for pilots, one contributor wrote: “Have any of you hand-flown an Airbus (or other aircraft heavy with fuel) at those flight levels even in smooth air? You are fighting to stay within the flying envelope . . . small margin for error on a good day, let alone a dark and stormy night.

“Take a jet aircraft and put it high, heavy, and run it through rough enough air and the laws of aerodynamics are waiting.”

In those laws, speed is a crucial factor. The thinner the air, the more speed needed for the wings to maintain their lift. Too slow: you stall.

At the same time, the faster the air passes over the wing, the more the centre of lift moves backwards, pushing the nose of the plane down. Too fast: you nosedive.

At high altitude the gap between those two critical speeds gets narrower and narrower. That’s coffin corner - and that was one of the crises facing the crew of AF447 as the plane plunged through the thunderheads in the early hours of last Monday.

It is now clear the crew, as they fought to stay airborne, no longer knew how fast their plane was travelling. According to Airbus and the accident investigators, the pilots’ instruments were giving “inconsistent” readings of the plane’s speed.

Did the crew or computer mistakenly think there was a danger of stalling? Did they power up, tipping the plane out of control and tearing it apart in the turbulence? Or did a violent updraft simply drive them too close to coffin corner?

Though no one yet knows for sure what destroyed the plane, investigators are concerned that it was not caused, as first suggested, by a lightning strike or a bomb or a meteorite. Instead they fear it was a fatal collision of high technology and the brute force of nature.

THE passengers who gathered at Rio de Janeiro’s airport last Sunday evening for AF447 spanned more than 30 nationalities, including five Britons. Eithne Walls, a young doctor from Belfast, was heading home from a holiday with two Irish doctors. Alexander Bjoroy, an 11-year-old boarder at Clifton College in Bristol, was returning after spending half term with his family. Two Brazilians, Bianca Machado Cotta, a doctor, and Carlos Eduardo de Melo Macario, a lawyer, had married the day before near Rio; they were off on honeymoon to Paris. Silvio Barbato, conductor of the Rio symphony orchestra, was leaving behind his violinist girlfriend, Antonella Pareschi. Later she said of Barbato: “He always used to tell me, jokingly, that he would not simply die, but disappear.”

If they worried about flying, they didn’t show it. Not so a Swedish family who had a habit of travelling separately in case disaster struck. Christine Schnabl boarded AF447 with her five-year-old son, Philipe; she left her husband to follow a few hours later with their three-year-old daughter on another flight. On such choices lives turn. The route from Rio to Paris passes through an area known as the ITCZ - the intertropical convergence zone - where hot, humid trade winds meet, creating storms with updrafts that can reach 100mph. Weather maps for that night show “numerous cumulonimbus towers rising to at least 51,000ft”, with thunderstorms and severe turbulence. But it was not exceptional.

Several hours after take-off AF447 went out of range of land radar and was heading across the Atlantic into the ITCZ. At night, pilots use onboard radar to spot storms ahead and divert sideways round them because they often rise too high to fly over. Did AF447 fail to spot a storm as it tried to find a way through the bad weather?

“Modern weather radar is very good,” said Guiver. “You get a good return [signal] off water droplets. The strength of return determines the colour you see on your screen: green, amber or red. Red is the core of the storm.”

At high altitude, however, the rain in a storm turns to ice crystals - and radar is much less effective at picking up ice.

Another danger is that, at the top of a storm, strong cross winds can blow turbulence out to one side, down-wind from the main updraft, in a formation known as an anvil.

“You always avoid a storm upwind of the core, or the anvil might catch you out,” said Guiver. If AF447 had accidentally hit an anvil, tossing it beyond its normal flying parameters, it could have made the autopilot disengage.

Crew error cannot be discounted. An internal Air France report, seen last week by The Sunday Times, said “the reliability of these [fly-by-wire] aircraft has the consequence of reducing the pilots’ appreciation of risk”. It warned against “complacency” and recommended that training should include more time on flight simulators.

Yet it seems unlikely to have been pilot error alone, especially since planes regularly cross the ITCZ and the crew of AF447 was experienced. At 58, Captain Marc Dubois had 11,000 hours of flying time. So did a malfunction precipitate or contribute to trouble? On the face of it, the A330 had an excellent safety record, with more than 550 planes built and no passenger fatalities since it went into service in 1993. Nevertheless, it has suffered some unnerving incidents.

Last October a Qantas A330 was flying at 37,000ft over Western Australia when it suddenly “pitched nose-down”, in the words of an official report. Henry Bishop, a passenger from Oxford, described the panic: “I feared for my life. It just fell hundreds of feet. It just fell forever and there were people flying everywhere.”

One crew member and 11 passengers were seriously hurt, and more than 100 suffered minor injuries before the pilot recovered control and made an emergency landing. A recent report on the incident found that one of the plane’s computers, known as Adiru (air data inertial reference unit), had “started providing erroneous data”. Back-up systems are in place, but other errors occurred and the “computers subsequently commanded the pitch-down movements”. Computers such as Adiru rely on data from sensors all over the aircraft. One that supplies information on airspeed is the pitot (pronounced “pee-toe”), a probe that measures the pressure of air rushing into it. If it gets blocked, it can start supplying incorrect information to the fly-by-wire system.

In 2001 an air worthiness directive for the A330, issued by the US Federal Aviation Administration, noted: “Unreliable airspeed may be caused by a radome [radar housing] destruction or obstructed pitots.”

The danger was illustrated only weeks later when a different model, an Airbus A319, suddenly found its instruments giving different airspeeds as it flew into Heathrow. At 6,000ft the autopilot disengaged without warning and the captain had to take manual control.

Though suspicions fell on the Adiru, no faults were found. Instead a pitot was discovered to have blockages, causing false speed readings.

There are also problems with the probes icing up in the freezing air at high altitudes, despite a heating system supposed to prevent it. One contributor to a pilot’s web-forum last week alleged: “The A330 is a beautiful aircraft but it has shown, again and again, very susceptible to probes icing.”

Did a pitot ice up and confuse the fly-by-wire system? Did the computers wrongly order more, or less, thrust?

What is clear is that the autopilot of AF447 disengaged and massive system failures rapidly followed. One minute later an Acars message reported “multiple faults regarding Adiru”.

Two minutes later flight control primary computer one failed, then flight control secondary computer one. Both those systems, however, have back-ups. Something far more drastic was also happening and the plane was out of control.

Four minutes after the autopilot disengaged, the cabin suddenly depressurised, perhaps with explosive force.

Although planes are designed to withstand enormous stresses, those caused by turbulence can be huge. That was demonstrated when an Airbus A300 flew into the wake of a Boeing 747 just after take-off from John F Kennedy airport in New York in November 2001. The turbulence - and the Airbus pilot’s attempts to correct for it - sheared off the A300’s rudder and vertical stabiliser. Without them the plane was doomed, and 265 people died.

Had AF447 suffered a structural failure? Did a window break or wing shear off? Whatever it was, the passengers must have been terrified. It was night over the Atlantic, lightning splitting the sky, the aircraft jolting in the turbulence, systems failing. Then massive decompression, cabin air gone and, outside, the temperature -30C or below. Mercifully they may not have suffered long.

As Philippe Juvin, a French doctor, explained: “If depressurisation is extremely brutal, you lose consciousness and a deep coma sets in. It would have been like falling asleep.”

INITIAL reports that wreckage from the plane had been spotted floating over a wide area have proved false, with the material turning out to be detritus from ships. Last night, however, the Brazilian air force reported that it had found two male bodies from AF447.

The search will continue with a French submarine heading for the area. The aircraft’s two “black box” data recorders - one for flight data; the other for cockpit voice recordings - can withstand immersion up to nearly 20,000ft and emit an audio beep for up to a month. But the chances of finding them must be slim in an area where the ocean floor is mountainous and up to 9,000ft deep.

Investigators admit that, without the black boxes, the full causes of the crash may remain elusive. But yesterday Airbus revealed that the Acars messages had pointed to 24 errors in the fly-by-wire system. It said: “There was inconsistency between the different measured airspeeds.” It also emerged that Air France is now replacing pitot tubes on all its medium- and long-haul jets - which it had previously been advised to do but had failed to carry out.

That will come as little comfort to Marie-Noëlle Linguet, whose husband Pascal was on AF447. He had just posted a card to his wife. Shortly before he boarded the aircraft, he rang his wife to say he would be home before the card arrived.

When news broke that the plane was missing, Marie-Noëlle could barely comprehend it. “I didn’t believe it,” she said. “I keep seeing him on the plane.” He never made it home. All his widow now hopes is that his last words will.

Bluebird Aero opens new UAV facility

Bluebird Aero opens new UAV facility
The company looks to hire more workers to develop its tactical unmanned aerial vehicles.

Bluebird Aero Systems Ltd. yesterday dedicated its new unmanned aerial vehicle (UAV) factory at Kadima, which cost NIS 5 million to build. The new 2,000-square meter plant will employ dozens of workers for the development and production of advanced electronic systems and mini tactical UAVs.

Bluebird president and CEO Ronen Nadir founded the company in 2002. One of the company's UAVs weighs just one kilogram and can be launched within minutes from any location without the need for prior infrastructures or preparation. The UAV provides tactical mapping on demand services in near real-time.

The size and weight of the UAV, combined with the advanced command and control capabilities jointly developed with Rafael Advanced Defense Systems Ltd. enables the UAV to provide simple and effective solutions for homeland security applications, such as the protection of national infrastructures and energy lines, mass incident control, and locating hostile parties in an urban environment. The UAVs also have civilian applications, including traffic control, aerial observation of mass events, security of installations, and forest management.

Bluebird is a portfolio company of Athlone Global Security Ltd., which specializes in homeland security companies. Athlone is a US-Israeli holding company founded by IDF Major General (res.) Doron Almog. It owns 30% of Bluebird, after investing $7 million in the company last year.
