  •  "Gentlemen, thaw your chickens!" (6+ / 0-)

    Supposedly during WWII, one of the Allies adopted the chicken cannon to test their airplanes, and were horrified at the results.  The chickens tore through planes like missiles, and nothing they built seemed to have a chance of surviving a bird impact.  They called across the pond - don't remember which way - to the people who first came up with the chicken cannon, and were reminded that real birds don't generally operate at freezing temperatures.

      AFAIK bird-proofing did not become a real effort until the sixties or so. And then the concentration was on windshields, not engines.

      BTW I saw the Convair (General Dynamics) chicken cannon in operation during that time. A fresh chicken was trimmed to meet the specified weight and was put into a cardboard deli container that acted as a sabot. It's amazing what the impact will do to an unreinforced windshield. But the most amazing thing is the smell in the test area afterward.

      and it seems that it doesn't make much difference whether they're frozen or not.
