its research into ballistic-missile defense, and whose "hobby shop" (as such places were known) had invented the infrared sensors on the AOA.
But it was now part of an Air Force program whose coverall name was Cobra. It worked in coordination with the Cobra Dane radar at Shemya, and often flew in conjunction with an aircraft called Cobra Ball-a converted 707-because Cobra was the code name for a family of systems aimed at tracking Soviet missiles. The Army was smugly satisfied that the Air Force needed its help, though wary of ongoing attempts to steal its program.
The flight crew went through its checklist casually, since they had plenty of time. They were from Boeing. So far the Army had successfully resisted attempts by the Air Force to get its own people on the flight deck. The copilot, who was ex-Air Force, ran his finger down the paper list of things to do, calling them off in a voice neither excited nor bored while the pilot and flight engineer/navigator pushed the buttons, checked the gauges, and otherwise made their aircraft ready for a safe flight.
The worst part of the mission was the weather on the ground. Shemya, one of the western Aleutians, is a small island, roughly four miles long by two wide, whose highest point is a mere two hundred thirty-eight feet above the slate-gray sea. What passed for average weather in the Aleutians would close most reputable airports, and what they called bad weather here made the Boeing crew wish for Amtrak. It was widely believed on the base that the only reason the Russians sent their ICBM tests to the Sea of Okhotsk was to make life as miserable as possible for the Americans who monitored them. Today the weather was fairly decent. You could see almost to the far end of the runway, where the blue lights were surrounded by little globes of mist. Like most flyers, the pilot preferred daylight, but in winter that was the exception here. He counted his blessings: there was supposed to be a ceiling at about fifteen hundred feet, and it wasn't raining yet. The crosswinds were a problem, too, but the wind never blew where you wanted up here-or more correctly, the people who laid out the runway hadn't known or cared that wind was a factor in flying airplanes.
"Shemya Tower, this is Charlie Bravo, ready to taxi."
"Charlie Bravo, you are cleared to taxi. Winds are two-five-zero at fifteen." The tower didn't have to say that Cobra Belle was number one in line. At the moment, the 767 was the only aircraft on the base. Supposedly in California for equipment tests, it had been rushed here only twenty hours earlier.
"Roger. Charlie Bravo is rolling." Ten minutes later the Boeing started down the runway, to begin what was expected to be yet another routine mission.
Twenty minutes later the AOA reached its cruising altitude of 45,000 feet. The ride was the same smooth glide known by airline passengers, but instead of downing their first drinks and making their dinner selections, the people aboard this aircraft had already unbuckled and gone to work.
There were instruments to activate, computers to recycle, data links to set up, and voice links to check out. The aircraft was equipped with every communications system known to man, and would have had a psychic aboard if that Defense Department program-there was one-had progressed as well as originally hoped. The man commanding it was an artilleryman with a masters in astronomy, of all things, from the University of Texas. His last command had been of a Patriot missile battery in Germany. While most men looked at airplanes and wished to fly them, his interest had always been in shooting them out of the sky. He felt the same way about ballistic missiles, and had helped develop the modification that enabled the Patriot missile to kill other missiles in addition to Soviet aircraft. It also gave him an intimate familiarity with the instruments used to track missiles in flight.
The mission book in the Colonel's hands was a facsimile print-out from the Washington headquarters of the Defense Intelligence Agency (DIA) telling him that in four hours and sixteen minutes the Soviets would conduct a test firing of the SS-25 ICBM. The book didn't say how DIA had obtained that information, though the Colonel knew that it wasn't from reading an ad in Izvestia. Cobra Belle's mission was to monitor the firing, intercept all telemetry transmissions from the missile's test instruments, and, most important,
