ELI5: Explain Like I'm 5

A Book from the Sky

Have you ever heard the story about a book falling from the sky? Well, let me explain it to you in a way that you can understand.

Imagine you are playing outside, and suddenly you see something falling from the sky. It's a book! How did it get there? It's like magic, isn't it?

Now, let me tell you how it really happened. There's a special way of delivering things from the sky called air-dropping. It means that an airplane flies over a place and drops things out of it. This is done for many reasons, such as delivering supplies to people who live in remote places, or helping people during a disaster.

So, the book you saw falling from the sky was most likely air-dropped by an airplane. It's amazing how things can be delivered from above, isn't it?
