Scientists at NASA built a gun specifically to launch 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 backrest 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 US scientists for
sugg estions.

NASA responded with a one-line memo: "Defrost the chicken."
