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.
