Why the Sky?

Why did we wanted to bring our design up into the sky? People manage to measure the depth of the deepest ocean but no one have yet to measure the height of the sky. No one have an exact answer to where the sky stops. All we know for now is that 300kilometer above ground level is the outer space. But no one actually state how high anyone could get to the top of the sky. Our planet is orbiting around around our sun alongside other planets and this made us one galaxy. Beyond our galaxy, we also discover another galaxy which is the Andromeda Galaxy.

We can also conclude that we are not the only galaxy out there. With this we can concluded the sky has no limit. We can make vehicles that are so large as big as our planet, it will still fit into the space. This is why we wanted to make the vehicle able to fly.
