"That's where you come in," Vera went on. "But first perhaps I should show you something."

She reached down and pushed a button on the desk, causing the set of blinds along the side of the office facing the hangar to slowly rise. "I'd like you to see the Daedalus." She pointed out the window. "Perhaps then you will better appreciate its significance."

Through the glass was a massive hangar engulfed in white vapor, as cryogenic liquid hydrogen created clouds of artificial condensate, cold steam, that poured over the army of milling technicians. Above the haze, however, she could just make out two giant aircraft. Their wings started almost at the cockpit, then widened outward to the plane's full length, terminating abruptly just before the high tail assembly. Positioned side by side, they looked like huge gliders, except that beneath the wings were clusters of massive engines larger than any she'd ever seen before.

"So that's the prototype, the vehicle specified in the protocol."

They were stunningly beautiful. Maybe all high-performance aircraft looked sexy, but these possessed a unique elegance. The child's vision of the paper airplane reincarnated as the most powerful machine man had ever created.

"I thought you would like to witness the final preparations for our first hypersonic flight," Vera proceeded. "Thus far one of the planes, that one there on the left"— she pointed—"has been flown to Mach 4.5. Today's test will take it to the hypersonic regime, over fifteen thousand miles per hour."

They've leapfrogged the West, Eva was suddenly realizing. It's the X-30 spaceplane America dreams of building in the next century, except it's here now.

"From the looks of things, I'd say you're on schedule."

Vera clicked something on the desk and a blinking number appeared at the top of a video screen. It was the countdown. Liftoff was less than an hour away.

"Yes, so far there has been no hold. Even though today is overcast, with a low ceiling, we don't experience weather delays like the American space shuttle. In fact, this plane is virtually weather-proof, since it leaves from a runway just like a normal passenger jet."
