Yes, Wall Street was the big news. Yes, it was more vital to the overall American well-being than some islands that not a few of their number had to be shown on a map. But, no, damn it, the government didn't have the right not to tell the media what was going on. Some of them, though, realized that the First Amendment guaranteed their freedom to find things out, not to demand information from others. Others realized that the Administration was trying to end the affair without bloodshed, which went part of the way to calming them down. But not all of the way.
"My fellow Americans," Durling began for the second time in the day, and it was immediately apparent that, as pleasing as the events of the afternoon had been, the news this evening would be bad. And so it was.
There is something about inevitability that offends human nature. Man is a creature of hope and invention, both of which belie the idea that things cannot be changed. But man is also a creature prone to error, and sometimes that makes inevitable the things that he so often seeks to avoid.
The four B-1B Lancer bombers were five hundred miles offshore now, again spread on a line centered due east of Tokyo. This time they turned directly in, took an exact westerly heading of two-seven-zero degrees, and dropped down to a low-penetration altitude. The electronic-warfare officers aboard each of the aircraft now knew more than they had two nights earlier.
Now at least they could ask the right questions. Additional satellite information had fixed the location of every air-defense radar site in the country, and they knew they could beat those. The important part of this night's mission was to get a feel for the capabilities of the E-767's, and that demanded more circumspection.
The B-1B had been reworked many times since the 1970's. It had actually become slower rather than faster, but it had also become stealthy. Especially from nose-on, the Lancer had the radar cross section—the RCS—of a large bird, as opposed to the B-2A, which had the RCS of a sparrow attempting to hide from a hawk. It also had blazing speed at low-level, always the best way to avoid engagement if attacked, which the crews hoped to avoid. The mission for tonight was to "tickle" the orbiting early-warning aircraft, wait for them to react electronically, and then turn and run back to Elmendorf with better data than what they had already developed, from which a real attack plan could be formulated. The flight crews had forgotten only one thing. The air temperature was 31 degrees Fahrenheit on part of their aircraft and 35 on another.
Kami-Two was flying one hundred miles east of Choshi, following a precise north-south line at four hundred knots. Every fifteen minutes the aircraft reversed course. It had been up on patrol for seven hours, and was due to be relieved at dawn. The crew was tired but alert, not yet quite settled into the numbing routine of their mission.
The real problem was technical, which affected the operators badly. Their radar, sophisticated as it was, did them fewer favors than one might imagine. Designed to make the detection of stealthy aircraft possible, it had achieved its goal, perhaps—they didn't really know yet—through a number of incremental improvements in performance. The radar itself was immensely powerful, and being of solid-state construction, both highly reliable and precise in its operation. Internal improvements included reception gear cooled with liquid nitrogen to boost sensitivity by a factor of four, and signal-processing software that missed little. That was really the problem. The radar displays were TV tubes that showed a computer-generated picture called a raster-scan, rather than the rotating-analog readout known since the invention of radar in the 19305. The software was tuned to find anything that generated a return, and at the power and sensitivity settings being used now, it was showing things that weren't really there. Migratory birds, for example. The software engineers had programmed in a speed gate to ignore anything slower than one hundred thirty kilometers per hour, else they would have been tracking cars on the highways to their west, but the software took every return signal before deciding whether to show it to the operator, and if anything lay on or beyond that ring a few seconds later, it was plotted as a possible moving aircraft contact. In that way, two albatrosses a few thousand meters apart became a moving aircraft in the mind of the onboard computer.
It was driving the operators mad, and along with them the pilots of the two Eagle fighters that flew thirty kilometers outboard of the surveillance aircraft. The result of the software problem was irritation that had already transformed itself into poor judgment. In addition, with the current sensitivity of the overall system, the still-active streams of commercial aircraft looked for all the world like fleets of bombers, and the only good news was that Kami-One to their north was dealing with them, classifying and handing them off.
"Contact, one-zero-one, four hundred kilometers," a captain on one of the boards said into the intercom. "Altitude three thousand meters…descending. Speed five hundred knots."
"Another bird?" the colonel commanding the mission asked crossly.
"Not this one…contact is firming up."
Another aviator with the rank of colonel eased his stick down to take his bomber lower. The autopilot was off now. In and out, he told himself, scanning the sky ahead of him.
"There's our friend," one of the EWOs said. "Bearing two-eight-one."
Automatically, both pilot and copilot looked to their right. Unsurprisingly, they saw nothing. The copilot looked back in. At night you wanted to keep an eye on instruments. The lack of good external references meant you ran the risk of vertigo, the loss of spatial orientation, which all aviators feared. They seemed to be approaching some layered clouds. His eyes checked the external temperature gauges. Thirty-five, and that was good. Two or three degrees lower and you ran the risk of icing, and the B-1B, like most military airceaft, didn't have deicing equipment. Well, the mission was electronic, not visual, and clouds didn't mean much to radar transmission or reception.
But clouds did mean moisture, and the copilot allowed himself to forget that the temperature gauge was in the nose, and the tail was quite a bit higher. The temperature there was thirty-one, and ice started forming on the bomber's tailfin. It wasn't even enough to cause any degradation in the controls. But it was enough to make a subtle change in the shape of the aircraft, whose radar cross section depended on millimeter tolerances.
"That's a hard contact," the Captain said on Kami-Two. He worked his controls to lock on it, transmitting the contact to the Colonel's own display.
"Maybe another one now."
"I have it." The contact, he saw, was leveling out and heading straight for Tokyo. It could not possibly be an airliner. No transponder. The base course was wrong. The altitude was wrong. The penetration speed was wrong. It had to be an enemy. With that knowledge, he told his two fighters to head for it.
"I think I can start interrogating it more—"
"No," the Colonel replied over the 1C phones.
The two F-I5J fighters had just topped off their tanks and were well sited for the interception. The alpha-numeric symbols on the Kami's screens showed them close, and aboard the fighters the pilots could see the same display and didn't have to light off their own targeting radars. With their outbound speed of five hundred knots, and a corresponding speed on the inbound track, it wouldn't be long.
