Garry Hoy, a 38-year old lawyer and a senior partner at the Holden Day Wilson Law firm in Toronto, Canada, fell to his death on July 9, 1993, after he threw himself against a window on the 24th floor of the Toronto-Dominion Centre, in an attempt to prove that the glass was "unbreakable" to a group of visiting law students. He had apparently attempted this stunt many times in the past, having previously bounced harmlessly off the glass. His first attempt failed to damage the glass at all. On his second attempt the glass still didn't break but instead actually popped out of the window frame, and he fell over 300 feet to his death.
