 Why do Lloyd and Jones shoot at the narrator?
Jones (that's the co-pilot; I didn't quite catch his first name) is scarlet-faced, barrel-chested and gives the general appearance of belonging under the spreading chestnut tree, not in a metal bullet flinging itself out into airless space. I still don't know Jones' first name, though Pat spoke to him, and it sounded like Flants. Pat gave him a cigar he'd smuggled on board (no smoking was allowed on the ship), and Jones threw it away. I was too scared to turn around, but finally Jones and Lloyd came running over, and I got up enough nerve to look. "Where," said Jones, "are Pat and Kroger?"
