The Saturn V Rockets Were Nutballs
The Apollo Program's Saturn V was the tallest, heaviest, and most powerful rocket of all time. Duh, you might say—it'd have to be to launch dudes to the moon. But it's actually crazy to consider the true scale of these beasts, and the amount of go-juice they required to fly. They were about as tall as 36-story building, making them 60 feet taller than the Statue of Liberty.
They weighed about 400 elephants, give or take an elephant on a diet. And had one exploded on the launchpad, it would have scorched a 1,408 foot hole in the Earth. Yowza! These rockets were no joke, and no spacecraft has come close to rivaling them in four and a half decades.
