секретный шифр д-ра Тьюринга, O.B.E:
We measured their position to be about 600km above the ground, in the upper ionosphere, and they appear to be continuing upwards into the plasmasphere.
We found that the ionisation patterns in the ionosphere are quite structured. They flow in these tubular structures that are aligned with the Earth’s magnetic field. And they can then move of their own accord.
