The room had fallen silent for a long moment. Was this some kind of trap? he almost wondered, like the old days. No, he'd quickly concluded, this time Russia was different. He would have to trust Mikhail Sergeevich. Most of all, though, he was holding his life-long ambition in his hand. At last he replied, hope mingled with apprehension.

"I think we have no choice." He had looked up at the president's troubled eyes. "You have no choice."

"Unfortunately, I think you are right." He had sighed and turned his gaze to the blackness outside the snow- banked window. "Ve tyomnuyu noch, ya znayu. Yes, Andrei Petrovich. On this dark night, I finally know what we must do."

After one final vodka, they had set about devising the scenario that would change the world forever. . . .

The airflow around the model continued to accelerate, while laser holograms of its complex aerodynamics were now being converted by the computer into multi-colored graphic art. Androv watched the wall-size liquid crystal display screen in the control room begin generating a vivid depiction of the streams whirling past the model, simulating the incremental stages of hypersonic climb. It was like watching a hallucination, he thought, as colors swirled around the fuselage of an object seemingly composed of 3-D lines and curves.

"We are now at Mach 6, Comrade Doktor Androv." The voice of a Soviet technician interrupted his thoughts. "The laser data show that the supersonic wave drag peaks at Mach 3.8, then subsides. Your new canard foreplanes appear to be working, at least for this portion of the flight envelope."

Androv studied the screen, noncommittal. "Thus far it would appear to be so. Perhaps the SX-10 was correct. All the same, at Mach 7, I want to switch on the enhancer, then capture those data and analyze them to be doubly sure."

The hypersonic enhancer permitted wind-tunnel burst tests at far higher velocities than a conventional facility could achieve. More high tech.

"There could still be a problem," Androv continued, "when the vortex of air currents shed from the nose of the fuselage encounters the shock waves from the wings, particularly around Mach 11." He turned to Ikeda. "Those vortexes have been responsible for significant damage to several American space shuttles during reentry phase. I need to see the data."

"As you wish." The director walked to the thick glass window that looked out onto the model suspended in the airstream. The crew of technicians hovered over the controls, watching for any signs of vibration. He studied the screens for a few moments, then spoke quietly to the head of the technical team, an intense young man in spectacles. This lieutenant turned and passed the order to his colleagues, who nodded gravely and stationed themselves at the switches.
