If a Saturn V rocket had ever exploded on the launchpad, it would have been a catastrophic event. NASA engineers once calculated that the resulting fireball would have been 1048 feet wide and would have hit temperatures as high as 2,500 degrees Fahrenheit. In the hopes of not losing astronauts or launch crew to the inferno, NASA tricked out the Apollo launchpad with some safety systems that still exist today, including an underground, rubber-lined bunker that was accessible from the launch platform via a 200-foot twisty slide. (Which almost sounds like fun, until you consider the context.)
