Ray Bradbury: A Sound of Thunder
“A Sound of Thunder” is a short story by Ray Bradbury, first published on June 28, 1952, in Collier’s magazine, and later included in the collection The Golden Apples of the Sun (1953). In a future where time travel is possible, a company organizes safaris to the past.

Before departure, he is sternly warned: he must follow the instructions to the letter; even the slightest mistake could have irreversible consequences.
