WASHINGTON (AP) - Airplanes chew up birds all the time but sometimes the birds win.
That may be what happened Thursday in New York when a US Airways Airbus 320 made a crash landing in water only three minutes after taking off from LaGuardia International Airport. Flight 1549's pilot reported a "double bird strike" to air traffic controllers moments after taking off, and said he had lost thrust in both engines, said Alex Caldwell, a spokeswoman for the National Air Traffic Controllers Association.
Technically, that means the plane had struck - or been struck by - two birds, Caldwell said. But Air Line Pilots Association safety committee chairman Rory Kay said the pilot's message could easily have meant that the jetliner had ingested birds in both engines or that it had been struck by more than just two birds.
"It's not easy to count birds," Kay noted wryly, when you're taking off or landing and typical speeds can exceed 100 miles per hour. Federal Aviation Administration spokeswoman Diane Spitaliere said, "Bird strikes do happen from time to time."
She said there haven't been many major accidents due to birds strikes, "not in many years - not like this one. ... It's more common in general aviation - smaller aircraft."
FAA figures show 64,734 bird strikes to civil aircraft in the United States from 1990 to 2005 - about one strike for every 10,000 flights.
The administration requires pilots to report bird strikes, Spitaliere said. But Kay called birds "a definite Achilles heel" for aviation. A commercial airliner like the US Airways plane is most likely to encounter birds on takeoffs and landings because that's when the plane is flying at lower altitudes, Kay said.
Most of the time airliners are flying at 20,000 feet to 30,000 feet where birds are few in number. But below 5,000 feet is where planes run into trouble, Kay said. "There is no shortage of bird strike reports ... You just don't get to hear about them," said Kay, a Boeing 767 pilot who has been flying for 34 years.
