Scientists at Rolls Royce built a gun specifically to launch dead chickens at the windshields of airliners and military jets, all traveling at maximum velocity.
The idea is to simulate the frequent incidents of collisions with airborne fowl to test the strength of the windshields and the safety of jet engines. American engineers heard about the gun and were eager to test it on their newly designed planes.
Arrangements were made, and a gun was sent to the American engineers. When the gun was fired, the engineers stood shocked as the chicken hurled out of the barrel, crashed into the shatterproof shield, smashed it to smithereens, blasted through the control console, snapped the engineer’s backrest in two and embedded itself in the back wall of the cabin, like an arrow shot from a bow.
The horrified Yanks sent Rolls Royce the disastrous results of the experiment, along with the designs of the windshield and begged the British scientists for suggestions.
Rolls Royce responded with a one-line memo: “Defrost the chicken.”
