They were spaceships, huge by comparison with _Aesclipus Twenty_. They
floated as the Med Ship did. They did not drive. They were not in
formation. They were not at even distances from each other. They did
not point in the same direction. They swung in emptiness like
derelicts.

Calhoun jockeyed his small ship with infinite care. Presently there
came the gentlest of impacts and then a clanking sound. The appearance
out the vision port became stationary, but still unbelievable. The Med
Ship was grappled magnetically to a vast surface of welded metal.

Calhoun relaxed. He opened a wall panel and brought out a vacuum suit.
He began briskly to get it on.

"Things moving smoothly," he commented. "We weren't challenged. So
it's extremely unlikely that we were spotted. Our friends on the floor
ought to begin to come to shortly. And I'm going to find out now
whether I'm a hero or in sure-enough trouble!"

Maril said drearily, "I don't know what you've done, except--"

Calhoun blinked at her, in the act of hauling the vacuum suit up his
chest and over his shoulders.

"Isn't it self-evident?" he demanded. "I've been giving astrogation
lessons to these characters. I certainly didn't do it to help them
dump germ-cultures on Weald! I brought them here! Don't you see the
point? These are space ships. They're in orbit around Weald. They're
not manned and they're not controlled. In fact, they're nothing but
sky-riding storage bins!"
