46 Metin set the target of the American 757 transport currently descending to land at Incirlik Air Base in eastern Turkey. The one Firat had shown him in the basement along with Asli’s file. The satellites, each shaped like thick, three-by-four-meter books with two large solar wings, orbited at twenty-one thousand kilometers above the Earth. Metin’s software was loaded into the seven GPS satellites visible to the target aircraft. Inside each satellite, the software overrode the transmitter buffers without interrupting the core code. Metin had enhanced the control of his software. The clocked and encrypted output was redirected into a set of chained memory addresses. These weren’t linked to the on-board atomic clock built into each satellite. Instead, they were driven by the clock cycl
