#6 Garry Hoy
Like his colleague from the first paragraph, this Canadian lawyer was trying to prove a point and got himself killed. Hoy was showing to his apprentices the high quality of the building windows they were in. He claimed that the windows were unbreakable, which he tried to prove by throwing himself against the window. It didn’t break but it popped out of frame sending the lawyer on a fatal flight from the 24th floor to the courtyard.
