Chicken gun

A chicken gun is a large-diameter, compressed-air cannon used to test the strength of aircraft windshields and the safety of jet engines. A common danger to aircraft is that they collide with birds in flight. Most parts of an aircraft are strong enough to resist such a bird strike. Jet engines may sustain serious damage, however, and cockpit windows are necessarily made of transparent, thin materials and are a vulnerable spot.
