In the 1950s in America there was invented a chicken gun. What for?
A chicken gun is a large-diameter, compressed-air cannon used to fire dead chickens at aircraft components in order to simulate high-speed bird strikes during the aircraft's flight. Jet engines and aircraft windshields are particularly vulnerable to damage from such strikes, and are the most common target in such tests. Whole, dead, standard-size chickens, as would be used for cooking, are thought to accurately simulate a large, live bird striking a plane in flight.
