Scientists at NASA...
Scientists at NASA built a gun specifically to launch dead chickens at the
windshields of airliners, military jets and the space shuttle, all
travelling at maximum velocity. The idea was 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 windshield, smashing it to smithereens. The chicken blasted
through the control console, snapped the engineers backrest in two and
embedded itself in the back wall of the cabin, like an arrow shot from a
bow.
Horrified, the 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."
