Scientists at NASA have developed a gun for the purpose of launching dead chickens. It is used to shoot a dead chicken at the windshield of airline jet, military jet, or the space shuttle, at that vehicle’s maximum traveling velocity. The idea being, that it would simulate the frequent incidents of collisions with airborne fowl, and therefore determine if the windshields are strong enough to endure high-speed bird strikes.
British engineers, upon hearing of the gun, were eager to test it on the windshields of their new high-speed trains. However, upon firing the gun, the engineers watched in shock as the chicken shattered the windshield, smashed through the control console, snapped the engineer’s backrest in two, and embedded itself into the back wall of the cabin.
Horrified and puzzled, the engineers sent NASA the results of the experiment, along with the designs of the windshield, and asked the NASA scientists for any suggestions.
The NASA scientists sent back a brief response: "Thaw the chicken."
