Jet Crashes, No One Seriously Hurt

All 309 Aboard Survive Fiery Crash In Toronto Thunderstorm

Airbus spokeswoman Barbara Kracht said the A340 has never crashed before in its 13 years of commercial service.

Chris Yates, an aviation specialist with Jane's Transport magazine, said the A340 is a very popular "workhorse" among carriers serving Asian and trans-Atlantic routes, with a very good safety record.

Although it was too early to draw any conclusions about the accident, Yates said, "we're probably talking about a weather-related issue here."

Although modern airliners are safer than ever, he said, extreme conditions can still be dangerous, especially during takeoff and landing.

"You can never account for weather," Yates said. "A thunderstorm can happen anywhere — it comes down to the judgment of the air traffic controller and the skill of the pilot to determine whether it's appropriate to land or to divert elsewhere."

Tuesday's airplane crash in Toronto came exactly 20 years after an American disaster that focused renewed attention to wind shear, a natural phenomenon that can make airplanes drop out of the sky.

While the cause of the Toronto crash has not yet been determined, the fact that it happened during a thunderstorm raises the possibility of wind shear.

The 1985 airline crash at Dallas-Forth Worth airport, which killed more than 137 people, made dealing with wind shear "a national imperative" for the U.S. federal government, said Larry Cornman of the National Center for Atmospheric Research in Boulder, Colo.

Since then, he said Tuesday, systems to detect wind shear have been installed at almost all major airports in the United States. Cornman said the Canadian government investigated installing such systems during the 1990s, but added he did not know how many have been installed.

Wind shear is a sudden change in wind speed or direction. The most dangerous kind, called a microburst, is caused by air descending from a thunderstorm.

The last major jet crash in North America was on Nov. 12, 2001, when American Airlines Flight 587 lost part of its tail and plummeted into a New York City neighborhood, killing 265 people. Safety investigators concluded that the crash was caused by the pilot moving the rudder too aggressively.

Toronto's Lester B. Pearson International Airport handles over 28 million passengers a year. Located 17 miles west of Toronto in the town of Mississauga, it has three terminals. Air France operates out of Terminal 3.

Paris-based Air France-KLM Group is the world's largest airline in terms of revenue. It is the product of the French flagship airline's acquisition last year of Dutch carrier KLM. For the year ended in March, the company earned $443 million on revenues of $24.1 billion.

Air France-KLM operates a fleet of 375 planes and flies 1,800 daily flights, according to the company's Web site. In the last fiscal year, it carried 43.7 million passengers to 84 countries around the globe. That made it the largest European carrier in terms of the number of passengers carried.

The A340 is part of the A330/A340 family of six related aircraft, all sharing the same frame, manufactured by Airbus, which is 80 percent owned by European Aeronautic Defence & Space Co. Britain's BAE Systems PLC owns the rest.

The craft owned and flown by Air France is the A340-300. The plane, usually is equipped to carry 295 passengers, and fly 7,400 miles before refueling.

There are currently 237 of the A340-300 and its sister craft, the A340-200, in operation, according to the manufacturer.
