The steel beams are there because of structure, granted! So we going to have to look past the beams and look at why safety wasnt on top of the list knowing how it was structured. The Olympic committee or whomever deals with safety should have foreseen such a possibilty of an athletic going of track due to the new speeds being reached coming out of a turn. They should have had a net or better yet plexiglass going like 10 feet up for a just in case reason.
