Rocket science

Scientists at Rolls Royce, England built a gun specifically to launch
dead chickens at the wind shields of airliners and military jets all
travelling at maximum  velocity.

The idea is to simulate the frequent incidents of collisions with
airborne fowl to test the strength of the wind shields.

American engineers heard about the gun and were eager to test it on
the Wind shields of their new high speed trains.

Arrangements were made, and a gun was sent to the American engineers.

When the gun was fired, the engineers stood shocked as the chicken
hurled out of the barrel, crashed into the shatter-proof 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 Yanks sent Rolls Royce the disastrous results of the
experiment, along with the designs of the wind shield and begged the
British scientists for suggestions.

Rolls Royce responded with a one-line memo:

"Defrost the chicken."
