“It was starting to get dim outside, so you got to see your own reflection. And there is the Earth, and you can still see the Earth’s surface and the dark sky overhead. And I could then see my reflection in the window and in the retina of my eye the whole earth and the sky could be seen reflected. So I called all the crew members one by one and they saw it, and they said, 'oh wow'.”
