Tourists to Terra

"Tourists to Terra" by Mack Reynolds is a science fiction story about rich people from the future who travel back to Earth seeking thrills by participating in old-fashioned battles. The story is about a luxury spaceship crew that takes these tourists to experience exciting historical battles. But things get dangerous when their desire to experience genuine danger backfires, especially when they meet Diomed, a hero from Greek myths. The crew decides to push forward even further into the Earth's future after accidents and injuries, where they witness the horrors of a potential nuclear war and learn that blindly chasing excitement can lead to unexpected and devastating consequences, especially as they approach a time of atomic weapons.
