I have a thing about chickens

The FAA has a device for testing the strength of windshields 
on airplanes.  They point this thing at the windshield of 
the aircraft and shoot a dead chicken at about the speed the 
air- craft normally flies at it.  If the windshield doesn't 
break, it's likely to survive a real collision with a bird 
during flight.
     
The British had recently built a new locomotive that could 
pull a train faster than any before it.  They were not sure 
that its windshield was strong enough so they borrowed the 
testing device from the FAA, reset it to approximate the 
maximum speed of the locomotive, loaded in the dead chicken, 
and fired.  The bird went through the windshield, broke the 
engineer's chair, and made a major dent in the back wall of 
the engine cab.
     
They were quite surprised with this result, so they asked 
the FAA to check the test to see if everything was done 
correctly. The FAA checked everything and suggested that 
they might want to repeat the test using a thawed chicken.
