CN Tower: Struck by Lightning 3000 Times

CN_Tower_LightningThe CN Tower in Toronto, completed 40 years ago, is hit by lightning about 75 times a year. Fortunately, the nearly 1500 ft. high structure has a lightning protection system. The air terminals, conductors, and grounding electrodes were recently inspected and found to be none-the-worse for wear.
