Aircraft-Bird Encounters Rise

One bird strike made headlines, but many occur -- including Denver

The surprise water landing of a US Airways plane in the Hudson River last January. Investigations revealed that a major bird strike had knocked out at least one engine. All 155 passengers and crew survived, with few injuries, and Captain Chesley "Sully" Sullenberger became an instant hero, making the talk-show circuit and landing a book contract. It turns out that the very aircraft the Sullenberger ditched in the frigid Hudson,

Associated Press reporter Michael J. Sniffen has been looking into bird strikes and has unearthed some amazing figures -- ones we don't generally think about when we fasten our seatbelts low and tight about ourselves and make sure that are seats and tray tables are in their full upright positions. Sniffen reported:

"Airplane collisions with birds or other animals have destroyed 28 aircraft
since 2000, with New York's Kennedy airport and Sacramento International
reporting the most incidents with serious damage, according to Federal Aviation
Administration data posted...The FAA list of wildlife strikes, published on the
Internet, details more than 89,000 incidents since 1990, costing 11 people their
lives. Most incidents were bird strikes, but deer and other animals have been
hit on runways, too.

"The situation seems to be getting worse: Airplane collisions with birds
have more than doubled at 13 major U.S. airports since 2000, including New
Orleans, Houston's Hobby, Kansas City, Orlando and Salt Lake City. Wildlife
experts say increasingly birds, particularly large ones like Canada geese, are
finding food and living near cities and airports year round rather than
migrating.

"The figures are known to be far from complete. Even the FAA estimates its
voluntary reporting system captures only 20 percent of wildlife strikes. The
agency, however, has refused for a decade to adopt a National Transportation
Safety Board recommendation to make the reports mandatory.

"...The Federal Aviation Administration says there were about 65,000 bird
strikes to civil aircraft in the United States from 1990 to 2005, or about one
for every 10,000 flights....air traffic control towers routinely
alert pilots if there are birds in the area."

Alysia Patterson filed a Denver-specific AP report, in which she recounted that DIA "led the nation in bird and wildlife strikes last year" -- 318 during the first 11 months of 2008. Of some comfort to passengers, Patterson was told by the FAA's Mike Fergus that DIA has "an aggressive wildlife mitigation program, [and] pilots are more aware of the problem and more apt to report a strike."

Whenever I've felt a jolt when taking off from or approaching DIA, I have assumed that it was turbulence of some sort. Next time, I'll speculate (to myself, not to my seatmate) that it might be due to a bird strike.
