From Simple Beginnings

The rocket came slamming down the gravity corridor, getting dangerously close to the moon (at least from a mathematical perspective) before pulling back on the throttle and easing in to land like a feather on the pad. All in all, it had taken less than a minute, which was still thirty seconds too slow. The tinstars had the ship surrounded, and were about to start flooding it with sleeping gas when all the airlocks exploded out. Three of them were too slow to get out of the way and were crushed by the flying doors, and the rest were left retching by the foul gas that had come billowing out once the ship was opened. Things only got worse when someone finally panicked and fired off a shot from their gun, and it was discovered that the gas was flammable...

And THEN, that's when the alien drones showed up. Of course.
