Migratory Birds Shut Down Radar at Airport
The FAA said about 3,000 birds, probably geese, passed through Lambert Airport at 7 a.m., but the airport's radar erceived them as 3,000 aircraft. That shut down the St. Louis radar system, forcing the airport to resort to a local backup. The FAA's Kansas City Center had to take over temporarily until the St. Louis backup system was up and running. The FAA said it's working on technology to help radar systems discern birds from airplanes. For now, the equipment can't make the distinction.
