"Gasoline. It's a hydrocarbon fuel used downside, to power their land rovers. A freebie by-product from the petrochemical cracking. Atmospheric oxygen provides the oxidant. It's a bulky, toxic, volatile, flammable—explosive!—liquid at room temperature. For God's sake don't let any of those barrels get open."

"Yes, sir," promised the quaddie, clearly impressed with Leo's list of hazards.

The legged supervisor of the orbital pusher crews arrived at that moment in the bay, trailed by a gang of quaddies from his department.

"Oh, hello, Graf. Look, I think it was a mistake letting you talk me into ordering this load—we're going to have a storage problem—"

"Did you order this?" Leo demanded.

"What?" the supervisor blinked, then took in the scene before him. "What the—where are my fuel rods? They told me they were here."

"I mean did you, personally, place the order. With your own little fingers."

"Yes. You asked me to, remember?"

"Well"—Leo took a breath, and handed him the report panel—"you made a typo."

The super glanced at the report panel and paled. "Oh, God."

"And they did it," Leo gibbered, running his hands through what was left of his hair. "They filled it—I can't believe they filled it. Loaded all this stuff onto the shuttle without once questioning it, sent a hundred tons of gasoline to a space station without once noticing that it was utterly absurd. . . ."

"I can believe it," sighed the super. "Oh, God. Oh, well. We'll just have to send it back, and reorder. It'll probably take about a week. It's not like our fuel rod stocks are really low, in spite of the rate you've been using them up for that 'special project' you're so hushy-hush about."

I don't have a week, thought Leo frantically. I have twenty-four hours, maybe.

"I don't have a week," Leo found himself raging. "I want them now. Put it on a rush order." He lowered his voice, realizing he was becoming conspicuous.

The super was offended enough to overcome his guilt. "There's no need to throw a fit, Graf. It was my mistake and I'll probably have to pay for it, but it's plain stupid to charge my department for a rush shuttle trip on top of this one when we can perfectly well wait. This is going to be bad enough as it is." He waved at the gasoline. "Hey, kids," he added, "stop unloading! This load's a mistake, it's all gotta go back downside."

The shuttle pilot was just exiting the personnel hatch in time to hear this. "What?" He floated over to them, and Leo gave him a brief explanation in very short words of the error.

"Well, you can't send it back this trip," said the shuttle pilot firmly. "I'm not fueled up to take a full load. It'll have to wait." He shoved off to take his mandatory safety break in the cafeteria.
