Federal Aviation Administration issues warnings about safety hazards at O'Hare.

On September 24, 2009, a Chicago Tribune reporter wrote that federal inspectors found numerous safety violations at the busy Chicago airport, including debris on runways and excessive foliage that functioned to attract wildfowl.  It is believed by experts that several recent commercial crashes have resulted from jet engine damage caused by "ingestion" of flying ducks and geese, and the only crash of the Concorde was later attributed to debris on a runway.  The FAA also cited a "pattern of false statements" in the Chicago authority's self-inspection program.
