Higher yet—unfathomably far above, and yet only in "low" Earth orbit—were larger structures, moving more slowly, like the minute hands of great clocks. Linear constellations with fatter, brighter lights on their ends. One of them was sweeping across the sky directly south of her, and she knew she was already too late to catch it. But looking off to the west she saw another approaching, like a giant leg striding across the sky, its foot swinging downward, not yet planted. She didn’t even need to check the params to know that this was the hanger for her. But she ran the calculation anyway, partly to confirm her guess and partly as a courtesy to other aircraft in this crowded space that might be aiming for the same one.
