It won’t break, it won’t break. It broke

This one’s a little closer to home for me. In an attempt to prove to some prospective articling students that the glass in the Toronto Dominion centre was unbreakable, lawyer Garry Hoy threw himself against the glass window of his 24th story law firm. Having done this before several times, he expected to bounce off the glass. The first time he tried it on July 9th, 1993, he bounced off harmlessly. The second time, he knocked the window out of the frame and fell to his death.

So technically, while the windows were unbreakable, the frame wasn’t.
