Bird Strikes is a serious treat to aircraft- Federal expert says
Talk about unintended consequences. “Bird strikes” — or collisions between birds and aircraft — are increasing for two reasons, according to the federal government’s leading expert on the phenomenon: The environment is cleaner and airplanes are quieter.
Increasing of birds populations, quiter jets contribute, federal says...
More than 200 people have been killed worldwide as a result of wildlife strikes with aircraft since 1988, according to Bird Strike Committee USA, and more than 5,000 bird strikes were reported by the U.S. Air Force in 2007. Bird strikes, or the collision of an aircraft with an airborne bird, tend to happen when aircraft are close to the ground, which means just before landing or after take-off, when jet engines are turning at top speeds.
The incidents are serious particularly when the birds, usually gulls, raptors and geese, are sucked into a jet engine and strike an engine fan blade. That impact displaces the blade such that it strikes another blade and a cascade can occur, resulting in engine failure.
A 12-pound Canada goose striking an aircraft going 150 mph at lift-off generates the force of a 1,000-pound weight dropped from a height of 10 feet, according to Bird Strike Committee USA.
