NASA engineers build a cannon that launches dead chickens at the windshields of airplanes, military jets and such to test the strength of the windshields against collisions with airborne fowl.British engineers are eager to test it on the windshields of their new high-speed trains. Arrangements are made, and a cannon is sent to the British engineers.When the cannon goes off, the engineers stand shocked as the chicken crashes into the shatterproof shield, smashes it to smithereens, blasts through the control console, snaps the pilot's backrest in two, and embeds itself in the back wall of the cabin.The horrified Brits send the Americans a report of the disastrous results, along with an urgent request for suggests on improving the windshield design.The American engineers respond with a one-line memo: "Thaw the chicken."
