was a graduating class, already commissioned,
having a final informal get-together.

The officer, who wore the three-orbit insignia of a major, was lean and
trim. His short-cropped hair covered his head like a gray fur skull cap.
One cheek was marked with the crisp whiteness of an old radiation burn.

"Stand easy," he ordered briskly. "The general instructions of the
Special Order Squadrons say that it's my duty as senior officer to make a
farewell speech. I intend to make a speech if it kills me--and you, too."

The dozen new officers facing him broke into grins. Maj. Joe Barris had
been their friend, teacher, and senior officer during six long years of
training on the space platform. He could no more make a formal speech
than he could breathe high vacuum, and they all knew it.

Lt. Richard Ingalls Peter Foster, whose initials had given him the
nickname "Rip," asked, "Why don't you sing for us instead, Joe?"

Major Barris fixed Rip with a cold eye. "Foster, three orbital turns,
then front and center."

Rip obediently spun around three times, then walked forward and stood at

"Foster, what does SOS mean?"

"Special Order Squadrons, sir."

"Right. And what else does it mean?"

humble, but it didn't work. By tradition, the Planeteers were the
cockiest gang that ever blasted through high vacuum.

Major Barris shook his head sadly. "You admit you're a simp, Foster. The
rest of you are simps, too, but you don't believe it. You've finished six
years on the platform. You've made a few little trips out into space.
You've landed on the moon a couple of times. So now you think you're
seasoned space spooks. Well, you're not. You're simps!"

Rip stopped grinning. He had heard this before. It was part of the
routine. But he sensed that this time Joe Barris wasn't kidding.

The major absently rubbed the radiation scar on his cheek as he looked
them over. They were like twelve chicks out of the same nest. They were
about the same size, a compact five feet eleven inches, 175 pounds. They
wore belted, loose black tunics over full trousers which gathered into
white cruiser boots. The comfortable uniforms concealed any slight
differences in build. All twe
