So this week I was reading Burnt Worlds, a science fiction novel by S.J. Madill, in which the spaceship Borealis tests out a new hyperspace jump drive by leaping 35,000 light years away from home, whereupon said jump drive promptly explodes, leaving the ship facing a multi-year journey to get back. Of course, they only packed enough supplies for a day trip. Whoops.
