Aircraft models used in China to scare away birds at airports
6 July 2005

Chinese researchers have resorted to aircraft models in a bid to prevent wild birds from disrupting flights at airports. A research team at the Harbin Institute of Technology (HIT) equipped the aircraft models with computer chips programmed to emit a variety of different birdcalls and high-frequency flashing lights. The models, with a three-meter wingspan, can fly up to 80 meters in height and is controlled by a human operator on the groud. By switching the plane models to the sounds of predators of birds currently in residence near runways, the operator is very likely to dispel birds from around airports. (Xinhuanet)
