the RAF had a chicken gun, it was a catapult contraption that sat at the end of a test runway and fired chickens (dead and plucked i presume) at light speed into the jet engines and canopys of planes(grounded planes that is) to test for bird strikes

. . . and British Rail borrowed it to test the high speed train. Concerned by the devestation it caused on the first tests they phoned the RAF about the problem.

After a quick check of their data the RAF replied "You're supposed to defrost the bloody chickens!"
