"Here or at the assembly plant," Scott agreed with a nod. Mainly they were waiting now for nonvisual data. The only KH-I2 satellite in orbit was approaching Japan and already programmed to look at one small patch of a valley. The visual information had given them a very useful cue. Another fifty meters of the rail spur had disappeared from view between one KH-n pass and another. The photos showed the catenary towers ordinarily used for stringing the overhead power lines needed for electrically powered trains, but the towers did not have wires on them. They had possibly been erected to make the spur look normal to commuters who traveled the route in the Bullet Trains, just one more exercise in hiding something in plain sight.

"You know, if they'd just left it alone…" the AMTRAK guy said, looking at the overheads again.

"Yeah." Betsy responded, checking the clock. But they hadn't. Somebody was hanging camouflage netting on the towers, just around the first turn in the valley. The train passengers wouldn't notice, and, given slightly better timing, the three of them wouldn't have either. "If you were doing this, what would you do next?"

"To hide it from you guys? That's easy," the executive said. "I'd park track-repair cars there. That way it would look ordinary as hell, and they have the room for it. They should have done it before. Do people make mistakes like this all the time?"

"It isn't the first," Scott said.

"And now you're waiting for what?" the man asked.

"You'll see."

Launched into orbit eight years earlier by the Space Shuttle Atlantis, the TRW-built KH-12 satellite had actually survived far beyond its programmed life, but as was true of many products made by that company—the Air Force called it "TR-Wonderful"—it just kept on ticking. The radar-reconnaissance satellite was completely out of maneuvering fuel, however, which meant you had to wait for it to get to a particular place and hope that the operating altitude was suitable to what you wanted.
