"It's not well known today, but the original Manhattan Project that constructed the first atomic bombs had quite an international character," said Berg. "It even included German, Italian, and Hungarian elements though the United States was at war with those countries."

"Come along and we'll get you settled in your quarters," invited Isaacson.

Lancaster followed him down the long hallways, rather dazed with the whole business. He noticed that the space station had a crude, unfinished look, as if it had been hastily thrown together from whatever materials were available. That didn't ring true for a government enterprise, no matter how secret.

Berg seemed to read his thought again. "We've worked under severe handicaps," he said. "Look, just suppose a lot of valuable material and equipment were ferried into space. If it's an ordinary government deal, you know how many light-years of red tape are involved. Requisitions have to be filled out in triplicate, every last rivet has to be accounted for—there'd simply have been too much chance of a rebel spy getting a lead on us. It was safer all around to use whatever chance materials could be obtained from salvage or through individual purchases on other planets. Ever hear of the Waikiki?"

"Ummm—seems so—wasn't she the big freighter that disappeared many years ago?"

"That's the one. A meteor swarm struck her on the way to Venus. Furthermore, one of them shorted out her engine controls, so that she swooped out of the ecliptic plane and fell into an eccentric skew orbit. When this project was first started, one of our astronomers thought he'd identified the swarm—it has a regular path of its own about the sun, though the orbit is so cockeyed that spaceships hardly ever even see the things. Anyway, knowing the orbit of the meteors and that of the Waikiki at the time, he could calculate where the disaster must have taken place—which gave us a lead in searching for the hulk. We found it after a lot of investigation, moved it here, and built the station up around it. Very handy. And completely secret."
