This comes from a friend of mine who's a retired VP from Boeing. He claims that there's more than a grain of truth to this...
___________________________________________________

Scientists at NASA built a gun specifically to launch a 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.

"DEFROST THE CHICKEN."
 
The fun to this one was the shows on MythBusters about it. They built a compressed air cannon and blasted chickens out of it, tons of nasty fun.
 
That was a really good mythbusters episode. If i remeber right though there wasn't that great of a difference in destruction between a frozen and thawed chicken though.
 
That was one of the Mythbusters' greatest episodes!

In the early rounds they found that the chickens obliterated their test targets in either state. /ubbthreads/images/graemlins/blush.gif Scrambling for some kind of useful outcome they did a secondary experiment based on momentum/energy transfer.

The momentum experiment showed no difference between states but that argument was seriously flawed. Ask anybody who's ever been beaned by both a hardball and a softball and they can tell you that. /ubbthreads/images/graemlins/crazy.gif

After a bunch of emails pointing out the error they revisited the subject in a later episode. With a new experiment measuring penetration depth through multiple layers of impact resistant glass they found that the frozen chickens were indeed much more destructive. /ubbthreads/images/graemlins/devilgrin.gif


PC.
 
Strange, when I first heard that story it was the engineers at Rolls Royce sending the gun to the USA, but hey, I'm biased! /ubbthreads/images/graemlins/wink.gif
