Sure, there were other astronauts. There were ten or twelve working on other projects, but the plasma space engine isn't an ordinary spaceship that anybody can take on a 150,000,000-mile round trip without rigorous training.

I reached the gate that separated spacemen from mere Earthlings and flashed my badge on the security guard.

"William Drake," he said, grinning. "Sure hope you have luck today, Mr. Drake."

"Thanks," I said. "How's Zinder doing?"

"Very well, the last I heard. The boys coming off the last Operations shift said he'd handled everything pretty well."

I went through the gate. Almost anybody can get through this one, but there are other security officers, at other gates further on down, to keep the place from being overrun by tourists, newspaper guys and people looking for rest rooms. How far you got depended on the color of your badge. Mine was blue, for the wild blue yonder, and I could walk right into Dr. Spartan's office with it, provided I had business there. And I wouldn't dare call on Dr. Spartan unless I did have it. He could eat a man out better than acid.

Finally I reached the bunker. I glanced into the room filled with the Operations staff which was keeping track of Willy—communicating with him, tabulating his heartbeats, respiration and maybe his thoughts—and checking the behavior of his capsule. I wasn't interested in them. I went to the end of the hall, flashed my badge again, and entered the room reserved for the panel that was going to pass or flunk Willy Zinder.

Doc Spartan was the man in charge. He was the leader of our little group, but that was no break for Willy Zinder. Doc Spartan was an old space hand. He'd been to the moon and he had conducted the trial flight of the plasma engine. First, last and middle, he was a perfectionist. I hated him, so did everyone else, but there was one thing that we all could say: if Doc stamped you okay, you were as good as he expected to find. And there was another thing that could be said: Doc Spartan made a top sergeant of the Marine Corps look like Peter Pan.

He was there, along with three other men who looked as if they'd been without sleep for a week. Maybe they'd taken a few naps during the twenty-four hours, but it didn't show. They were red-eyed, their hair was uncombed and they each showed a day's growth of beard. Although the room was air-conditioned, they looked sweaty and hot. Mugs full of black coffee were on their desks and there were bread crusts and half-eaten sandwiches on trays nearby.

Axel Ludson stood back against the rear wall. Like me, he had nothing to do but watch and he had probably hurried over after eating breakfast, just as I had, in order to be on hand when Willy made his re-entry.
