NASA Scientists built a gun specifically to launch four pound dead chickens, all traveling at maximum velocity, at the windshields of airliners, military jets and the space shuttle. This was to test the strength of the windshields in simulations of the frequent incidents of collisions with airborne fowl.
British engineers heard about the gun and were eager to test it on the windshields of their new high speed trains. Arrangements were made, and a gun was sent to the British engineers. When the gun was fired, the engineers stood shocked as the chicken hurled out of the barrel, crashed into the 'shatterproof' shield, smashing it to smithereens, blasted through the control console, snapped the engineer's back-rest in two and embedded itself in the back wall of the cabin.
The horrified Brits sent NASA the disastrous results of the experiment, along with the designs of the windshield and begged the US scientists for suggestions.
NASA responded with a one-line memo --
"Defrost the chicken."
