I’m confident the copper skin and the stainless steel frame is connected at multiple locations with copper strapping and the entire structure is grounded.
Alas, if one reads a bit lower and looks closely, the lady only appears to have been struck. The lightning clearly hits behind the statue. If electricity follows the path of least resistance, it doesn’t make sense for her to have been struck in the chest area.
Nice picture. But I thought it looked like the lightning struck behind her before I read any comments. Whether it’s photoshopped I don’t know.
By the way, lightning is so brief that even small copper conductors will often carry it without damage. Telephone wire, which is 24 AWG or about half a millimeter in diameter, is sometimes damaged but often not. The wire is heated by Ohmic resistance while carrying the current, which can be thousands of amperes, but because of its specific heat capacity this has to go on for a long enough time to make its temperature threaten it. Lightning is so brief this often doesn’t happen. For things that are orders of magnitude more resistive, like trees, it generally turns out differently.
