The fastest animal on Earth isn't the cheetah, it's a bird folding its wings and falling

A peregrine falcon hunts by climbing high above its prey, then tucking its wings into a steep dive called a stoop, reaching speeds recorded over 200 mph, faster than a Formula 1 car. Researchers studying the aerodynamics of the dive found falcons make small, continuous course corrections throughout the fall rather than dropping in a straight line, letting them intercept fast, maneuvering prey in midair.
