RE: [TCML] x-ray transformer for Tesla supply, chickens
For those who don't know what chicken gun is.
Chicken gun is used to stimulate impact of birds on moving airplanes and other air moving vehicles, especially frontal cockpit glass and wing structure. This is done by loading a hopefully dead chicken into a special accelerator a.k.a. chicken gun and shooting it at targets stimulating high velocity speeds.
Of course the real trick behind this is not to forget to defrost the chicken, as there were multiple cases where frozen chicken was found going half way in to the airplane :o) hehehe

I'm not sure what a chicken gun is, but I know what happened to a several
neighborhood's PC's in Santa Barbara when some idiot shot a real gun into a
"Pole Chicken" on New Year's eve to watch the sparks.

Hopefully the topic will be short and quick and Chip will allow this
non-Tesla question by:
what on earth is a "chicken gun" and why would you "shoot chickens"?
