Why Isn't It Faster To Fly West?

The video explains how the Earth's rotation affects airplane travel. At the equator, the Earth's surface moves east at 1000 mph, while at 45° latitude, it moves at 700 mph. Airplanes must move relative to the air, adding or subtracting speed based on direction. Despite the Earth's rotation, travel times vary due to upper atmospheric winds like the jet stream, influenced by the Coriolis effect. This effect is due to different Earth parts moving at varying speeds because of its round shape and rotation.

Why do airplanes have to move relative to the air to reach their destinations?

Explain the Coriolis effect and its impact on airplane travel.
