Data Pod, Data Pod!!!

Anyone who had fallen into the sea from an altitude of ten thousand meters knew this.

When you were high enough and moving fast enough, the water felt harder and harder when you hit it.

Generally, a fall from over a hundred meters had an effect that was basically equivalent to hitting concrete.

A lot of clickbait accounts and so-called science bloggers would tell you it was because of water's surface tension, but that wasn't actually the case.

The real reason was that, under normal conditions, water was incompressible and had inertia.

For example.

What happened when you stuck your finger into water?

Your finger occupied the space where the water had been. The water was pushed aside, making room for your finger.

The water beside it was still incompressible and couldn't merge with it, so it could only squeeze the water elsewhere, making it bulge at the surface.

In other words, putting a finger into water pushed aside a volume of water equal to the volume of that finger, with no time for the water to cushion the impact.

That was why slow movement produced ripples, while fast movement sent water splashing everywhere.

That was what happened when a human body entered the water. It didn't take much force for the water to move aside in 0.1 seconds, but if you were moving too fast and needed the water to move aside in 0.0001 seconds, the force from the water's inertia became enormous—more than the human body could withstand.

The DF-2 was no different.

It hit the water at nearly Mach 10. The instant it encountered the water's inertial force, cracks appeared across its surface because its structure couldn't bear the strain.

In a very short time.

Crack, crack, crack.

The cracks rapidly spread across the entire surface of
