The Great Slide down from the Stadium Above the Clouds was great. The tallest in the solar system, the slide was made from Graphite42, a metal that was completely friction-free, and Pip whooshed down it at what felt like over a thousand kilostrands a minute! And the view, as she approached the City from above, was fantastic! She was nearly at the bottom when . . . I would like to know what " kilostrands" here mean? It should be a fictional word, but i would like to know how fast it refers. Thanks.
