Forward, the EWO displays were coloring up. The rectangular TV-type tube displayed a computer memory of every known radar installation on Japan's western coast. It hadn't been hard to input the information, as most of them had been established a generation or two earlier by Americans, back when Japan had been a massive island base for use against the Soviet Union and liable to Russian attack for that reason. The radars had been upgraded along the way, but any picket line had its imperfections, and these had been mostly known to the Americans beforehand, and then reevaluated by ELINT satellites in the last week. The aircraft was heading southeast now, leveling out two hundred feet over the water and tooling along at its maximum low-level speed of three hundred fifty knots. It made for a very bumpy ride, which the flight crew didn't notice, though everyone else did. The pilot wore low-light goggles, and swept his head around the sky while the copilot concentrated on the instruments. The latter crewman was also provided with a head-up display just like that on a fighter. It displayed compass heading, altitude, airspeed, and also gave him a thin green line to indicate the horizon, which he could sometimes see depending on the state of the moon and clouds.

"I have strobes very high at ten o'clock," the pilot reported. Those would be airliners on a standard commercial routing. "Nothing else."

The copilot gave her screen another look. The radar plot was exactly as programmed, with their flight path following a very narrow corridor of black amid radial spikes of red and yellow, which indicated areas covered by defense and air-control radars. The lower they flew, the wider was the black-safe zone, but they were already as low as they could safely fly.

"Fifty miles off the coast."

"Roger," the pilot acknowledged. "How're you doing?" he asked a second later. Low-level penetrations were stressful on everyone, even with a computer-controlled autopilot handling the stick work.

"No prob," she replied. It wasn't exactly true, but it was the thing she was supposed to say. The most dangerous part was right here, passing the elevated radar site at Aikawa. The weakest part of Japan's low-level defense perimeter, it was a gap between a peninsula and an island. Radars on both beams almost covered the seventy-mile gap, but they were old ones, dating back to the 1970's, and had not been upgraded with the demise of the Communist regime in North Korea. "Easing down," she said next, adjusting the altitude control on the autopilot to seventy feet. Theoretically they could fly safely at fifty over a flat surface, but their aircraft was riding heavy, and now her hand was on the sidestick control, itself another illusion that this was actually a fighter plane. If she saw so much as a fishing boat, she'd have to yank the aircraft to higher altitude for fear of a collision with somebody's masthead.
