"I know." Ryan even knew where the leak would start, and the only reason it hadn't happened already was the FBI. "But we need to keep them dumb just a little longer."

It started cautiously, not really as part of any operational plan at all, but more as a precursor to one. Four B-1B Lancer bombers lifted off from Elmendorf Air Force Base in Alaska, followed by two KC-10 tankers. The combination of latitude and time of year guaranteed darkness. Their bomb bays were fitted with fuel tanks instead of weapons. Each aircraft had a crew of four, pilot and copilot, plus two systems operators.

The Lancer was a sleek aircraft, a bomber equipped with a fighter's stick instead of a more conventional control yoke, and pilots who had flown both said that the B-1B felt and flew like a slightly heavy F-4 Phantom, its greater weight and larger size giving the bomber greater stability and, for now, a smoother ride. For the moment the staggered formation of six flew international route R-220, maintaining the lateral spacing expected of commercial air traffic.

A thousand miles and two hours out, passing Shemya and leaving ground-control radar coverage, the six aircraft turned north briefly. The tankers held steady while the bombers one by one eased underneath to take on fuel, a procedure that lasted about twelve minutes in each case. Finished, the bombers continued southwest while the tankers turned to land at Shemya, where they would refill their own tanks.

The four bombers descended to twenty-five thousand feet, which took them below the regular stream of commercial air traffic and allowed more freedom of maneuver. They continued close to R-220, the westernmost of the commercial flight tracks, skimming down past the Kamchatka Peninsula.

Systems were flipped on in the back. Though designed as a penetrating bomber, the B-1B fulfilled many roles, one of which was electronic intelligence. The body of any military aircraft is studded with small structures that look for all the world like the fins on fish. These objects are invariably antennas of one sort or another, and the graceful fairing has no more sinister purpose than to reduce drag. The Lancer had many of them, designed to gather in radar and other electronic signals and pass them along to internal equipment, which analyzed the data. Some of the work was done in real-time by the flight crew. The idea was for the bomber to monitor hostile radar, the better to allow its crew to avoid detection and deliver its bombs.
