This just in. From the R&D hot-line.
Research in the UK regarding HSR development. In the US, NASA is involved.
Scientists at NASA built a high-compression air powered gun specifically to launch standard 4 lb. dead chickens at the windshields of airliners, military jets and the space shuttle, all traveling at their 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 corrective suggestions.
NASA responded with a one-line memo, "Defrost the chickens."
