While on the course at British Aerospace Woodford, I was told a story (they swore it was true)about the certification trials of the BAe 146 windscreen. The chicken was weighed and loaded up in the test cannon prior to the 250kt impact test. The technicians then went for lunch. When they returned, they finished setting the measurement equipment and fired the cannon. Chicken duly splatted on screen...together with a mass of black fur. When they examined the screen they discovered the sadly mangled carcass of a cat -which had crept in to eat the chicken while they were at lunch.
So if you are lucky enough to fly the 146, you can relax in the knowledge that the screen is tested for cat strike up to 250kts.
