Last year, a Royal Air Maroc plane made an emergency landing at Amsterdam's Schiphol Airport after it was hit by a flock of geese. They've been trying everything to get rid of the birds, they say, including "luring them away" (presumably with irresistible offers from Groupon).
Incidents like these have been increasing at the airport, so its directors are seeking permission from Brussels to shoot the birds as well as gas them with CO2. Birding groups are not happy.
