a space
ship could be built and powered and equipped with machinery there had to
be such wildly irrelevant plans worked out as a proper check of controls
for the piston-engine ships that flew parts to the job. The details were
innumerable!

But the job was still worth doing. Joe was glad he was going to have a
share in it.

It was a merely misty day. The transport plane stood by the door of a
hangar on this military field, and mechanics stood well back from it and
looked it over. A man crawled over the tail assembly and found one small
hole in the fabric of the stabilizer. A shell fragment had gone through
when the war rockets exploded nearby. The pilot verified that the
fragment had hit no strengthening member inside. He nodded. The mechanic
made very neat fabric patches over the two holes, upper and lower. He
began to go over the fuselage. The pilot turned away.

"I'll go talk to Bootstrap," he told the co-pilot. "You keep an eye on
things."

"I'll keep two eyes on them," said the co-pilot.

The pilot went toward the control tower of the field. Joe looked around.
The transport ship seemed very large, standing on the concrete apron
with its tricycle landing gear let down. It curiously resembled a
misshapen insect, standing elaborately high on inadequate supporting
legs. Its fuselage, in particular, did not look right for an aircraft.
The top of the cargo section went smoothly back to the stabilizing fins,
but the bottom did not taper. It ended astern in a clumsy-looking bulge
that was closed by a pair of huge clamshell doors, opening straight
astern. It was built that way, of course, so that large objects could be
loaded direct into the cargo hold, but it was neither streamlined nor
graceful.

"Did anything get into the cargo hold?" asked Joe in sudden anxiety.
"Did the cases I'm with get hit?"

After all, four rockets had exploded deplorably near the ship. If one
fragment had struck, others might have.

"Nothing big, anyhow," the co-pilot told him. "We'll know presently."

But examination showed no other sign of the ship's recent nearness to
destruction. It had been overstressed, certainly, but ships are built to
take beatings. A spot check on areas where excessive flexing of the
wings would have shown up--a big ship's wings are not perfectly rigid:
they'd come to pieces in the air if they were--presented no evidence of
damage. The ship was ready to take off again.

The co-pilot watched grim
