Scientists at NASA built a gun specifically to launch standard 4 pound dead
chickens at the windshields of airliners, military jets and the space
shuttle, 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.
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, smashed 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, like an
arrow shot from a bow.
The horrified Brits sent NASA the disastrous results of the experiment,
along with the designs of the windshield and begged the U.S. scientists for
suggestions.
NASA responded with a one-line memo --
"Defrost the chicken." (True Story)
