In the 60's many years before I went to work for Grumman Aircraft Engineering Corp in Bethpage, NY they used to cannon fire live chickens at Navy A6 canopies. That is till one day someone screwing around I'm told fired a chicken into a nearby adjacent property and it landed in a backyard. That was the end of the live bird testing. From then on it was thawed birds only. I don't know when Grumman stopped bird testing but when I started working there in 1979 it was no longer performed.
