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 US scientists
for suggestions.

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