I seem to remember the British starting to test airplane windshields, and getting horrible results, until their colleagues gave them a key piece of information about the waterfowl...
Anybody else remember this?
"He who fights with monsters might take care lest he thereby become a monster. And if you gaze for long into an abyss, the abyss gazes also into you." - Friedrich Nietzsche
That no man should scruple, or hesitate a moment to use arms in defense of so valuable a blessing [as freedom], on which all the good and evil of life depends, is clearly my opinion; yet arms ... should be the last resource. - George Washington

A chicken farmer in the next valley kept a lot of chickens right around the right weight. When he got word there'd be a chicken shot the next day, he'd pick out a bunch with the right weight, then make sure they ate just the right amount overnight.
He'd put twice as many as needed in his truck and run them to the shot site. At least the needed number would have shit themselves down to spec weight.
Procedure is to anesthetize the chicken (must be alive at impact) and stuff it into a paper machet projectile. The air canon could get the chicken up to over 400mph at impact. You clean up with a hose and a mop.
The U.S. government spent a lot of money trying to develop an artificial chicken, but was not successful.
