“A Sound of Thunder” by Ray Bradbury is a story where the main Character, Eckels, goes on a time safari that uses a time machine to transfer the hunters, Eckels, Billings, and Kramer and their leaders, Mr. Travis and Lesperance.
These hunters arrive sixty-million years ago to the time of the dinosaurs. In search of a Tyrannosaurus rex with a red paint mark. They are warned by Travis to stay on the metal path that is laid by the time safari because if they accidently step on a plant, animal etc. they would change the future.
They are also told that they cannot shoot at random animals. They only shoot at ones marked with red paint. Why do they have to shoot at marked animals? Lesperance answered this question by telling them that paint marked animals are doomed to die.
After they set foot on the path, they spotted the T-rex a while later and then they started shooting it. (Eckels didn’t listen to instructions and went off the path) After that, the dinosaur fell down and a tree fell on top of it, and Lesperance said that the tree was supposed to kill the T-rex.
They cleaned up the mess and in the morning just as they were about to leave, Travis was mad at Eckels and ordered him to get the bullets out of the large monster. If he didn’t they would leave him here.
After he got them, they were speeding back to present-day and Mr.Travis glared at him a full ten minutes. However, when they got back the place was different. Instead of Keith getting chosen for president, the other one got chosen and all the spelling on the sign was wrong. Just as Eckels was cleaning his boots, He saw a dead butterfly in the muck stuck on his shoe.
He wanted to make it alive again but it was too late. Travis lifted his rifle and shot Eckels.
