Health, safety, and capacity regulations were no friend of the Maracanã Stadium in Rio de Janeiro for the final of the 1950 World Cup. The official attendance was 173,380, but it's estimated that somewhere between 200,000 and 210,000 fans crammed in with hopes of watching Brazil lift their first World Cup. After going 1-0 up, it all fell apart and Uruguay took their second title with a 2-1 win.
