None of this would have made sense to her had she not been party to last night’s meeting in the main cabin. Obviously, they had never had any true intention of flying to Hainan Island. They had chosen that destination solely because it was a domestic flight and as such would not draw the attention of the immigration authorities at Xiamen’s airport. For that, any destination in China would have sufficed. But Hainan seemed to have another advantage, which was that a flight to there from Xiamen would naturally pass over the ocean; and over the ocean it was possible to get away with tricks such as screaming along at wavetop level to evade radar.
She reckoned that they were playing some kind of game having to do with the workings of the air traffic control system. Though she had never studied such things in any detail, she knew in a vague way that radar had limited range and that the structure of the air traffic control system somehow reflected that fact; a country’s airspace was divided into separate zones, each managed from a different control center with its own radar system. Airplanes in flight were handed off from one control center to the next as they made their way across the country. At some point they had stopped being the responsibility of the air traffic controllers in Xiamen and entered into a zone controlled from Hong Kong. Or perhaps by flying out over the ocean they had entered into a no-man’s-land that was not monitored or controlled by any authority. At any rate, she guessed that they had, a few minutes ago, reached one of those edges or seams in the system. Pavel and Sergei had then bid farewell to the air traffic controllers in the zone that they were departing and had gone into the power dive before they showed up on the radar screen, and came to the attention, of any other controllers.
Where they were going now she could only conjecture. Once they cleared the southern cape of Taiwan, there was nothing out there but the Pacific Ocean. But she’d seen enough of great circle routes yesterday evening to understand that flying basically east, as they were doing now, was no way to get across it.
It took them about half an hour’s flying time to get east of Taiwan. The plane then banked left again, and its little icon on the screen rotated around until it was pointed a little east of north. So it appeared that they were executing a large U-shaped maneuver around Taiwanese airspace.
The radio, which had been silent for a while, came alive again; apparently the pilots had switched over to a different frequency, and apparently that frequency was being used by Taipei Center, since all the transmissions now seemed to originate from there. Taipei Center seemed to be managing a large number of Boeings and Airbuses. These were helpfully identified, not only by their call signs, but by their origins or destinations as well, and so Zula got a clear impression of an extremely busy airport handling jumbo jets coming in from, or flying out to, far-flung destinations such as Los Angeles, Sydney, Tokyo, Toronto, and Chongqing.
It took rather less than an hour for the plane to clear the northern tip of Taiwan, which was where Taipei was located. It then executed a series of maneuvers and began a long steady ascent, which Zula was able to track using the helpful data screens thrown up every minute or so on the TV display. Presumably this would make the plane visible on radar, supposing that any radar stations were in range. But looking at the smaller-scale map that occasionally flashed up on the TV, Zula noted that they were in a region where planes from all over Southeast Asia and Australia might fly northward en route to Japan or Korea. So maybe they were hoping that their bogey would go unnoticed in all the clutter?
Her bladder could not stand any more waiting, and so she finally opened the door and stepped forward into the main cabin. This was crowded and smelled like sweaty men. The four soldiers were seated close together in the back. Two of them were napping, one was reading the Koran, and the fourth was intently focused on a laptop. At the cabin’s forward end, a fold-down table had been deployed and was covered with large aeronautical charts on which Khalid and Abdallah Jones had apparently been tracking their progress. Khalid was there now, staring directly at Zula with hate, fascination, or both. Jones was not in evidence until she made her way up the aisle to the lavatory. She then discovered him lying on his back with his feet in the aisle and his head in the cockpit. He was staring almost vertically upward through the cockpit windows. Pavel and Sergei likewise were craning their necks in what seemed a most awkward manner, attending to something that seemed to be above and ahead of them.
Zula used the lavatory. When she emerged, all three men were still in the same positions, though Jones had now begun cackling with satisfaction.
