back on for four, then sixteen off. Why?" "Well, a few of us are getting up a friendly little game before we go back on watch. I thought you might want to join us.""I know, but that's not what I'm after. I fly because I love flying. I use the flying pay just to keep up the extra premiums the insurance companies keep insisting on so long as I indulge my passion for fighter planes." "I guess about the only way you could get any regular flying on this job would be for a war to come along." "That's about it.

He had an hour to kill before going on watch, and this was as good a place as any to kill it. The lounge was almost empty. Most of the pilots must have been asleep. They couldn't all be in Mike's game. He leaned over a low table in the center of the room and started sorting through the stack of magazines. Looking for anything in particular, Harry?" He turned to face the speaker. "No, just going through these fugitives from a dentist's office to see if there's anything I haven't read yet. I can't figure out where all the new magazines go. The ones in here always seem to be exactly two months old." "Here's this month's _Western Stories_. I just finished it. It had some pretty good stories in it." "No, thanks, the
