One of the biggest enemies for a large jet airliner is still a bird. Birds can get sucked into an engine and especially during a crucial time like take off can cause a lot of havoc. According to the FAA from 1990 to 2007 there have been about 80,000 bird strikes, 11 people have died from the result of bird strikes, and bird strikes have cost almost $300 million in damages.
There have been many different methods used to get rid of flocks of birds around airports (sounds, sprays, killing, etc), but Southwest Florida International Airport is one of 20 airports trying something a little different: using a dog to keep the birds in line.
Thanks Kate for the tip!
