The U.S. Federal Aviation Administration (FAA) announced that serious runway incursions were down 50 percent for the most recent 12-month period compared to the previous year.
There were 12 serious incursions in fiscal year 2009 which ended Sept. 30, with only two involving commercial carriers, compared to 25 such events in fiscal year 2008, with nine involving commercial carriers. A runway incursion occurs when something or someone intrudes on a runway without authorization. A serious incursion is one in which a collision was narrowly avoided, or there was a significant potential for collision that resulted in the need to take quick corrective action. (FAA)
