There was a total of 37 active satellite up-link trucks using either microwave or Ku-band transmitters to generate a total of 48 active video, and 168 active audio signals, all feeding over a billion sports fans in seventy-one countries when the gamma and X-ray flux struck. In most cases, the impact generated a signal in the wave guides, but in six trucks, the traveling-wave tubes themselves were illuminated first and put out a gigantic pulse on exactly the proper frequencies. Even that was beside the point, however. Resonances and otherwise inconsequential irregularities within the wave guides meant that wide segments of the satellites orbiting over the Western Hemisphere were being worked by the TV crews at Denver. What happened to them is expressed simply. Their sensitive antennas were designed to receive billionths of watts. Instead, they were suddenly bombarded with between one and ten thousand times that on many separate channels. That surge overloaded an equal number of the front-end amplifiers inside the satellites. The computer software running the satellites took note of this and began to activate isolation switches to protect the sensitive equipment from the spike. Had the incident affected merely one such receiver, service would have been restored at once and nothing further would have happened, but commercial communications satellites are immensely expensive artifacts, costing hundreds of millions of dollars to build, and hundreds of millions more to launch into orbit. When more than five amplifiers recorded spikes, the software automatically began shutting circuits down, lest possibly serious damage to the entire satellite result. When twenty or more were affected, the software took the further step of deactivating all onboard circuits, and next firing off an emergency signal to its command ground station to say that something very serious had just happened. The safety software on the satellites were all customized variations of a single, very conservative program designed to safeguard billions of dollars' worth of nearly irreplaceable assets. In a brief flicker of time, a sizable fraction of the world's satellite communications dropped out of existence. Cable television and telecommunications systems all ceased, even before the technicians who managed their operations knew that something had gone disastrously wrong.

Pete Dawkins was resting for a moment. He thought of it as protecting the armored truck. The Wells Fargo guard was off delivering another few hundred pounds of quarters, and the police officer was sitting, his back against the shelves full of coin bags, listening to his radio. The Chargers were coming up to the line for a third-and-five at the Vikings' forty-seven. At that moment, the darkening sky outside turned incandescent yellow, then red - not the friendly, gentle red of a sunset, but a searing violet that was far brighter than that color could possibly have been. His mind barely had time to register that fact when it was assaulted by a million other things at once. The earth rose beneath him. The armored car was tossed up and sideways like a toy kicked by a child. The open rear door was slammed shut as if struck by a cannon. The body of the truck sheltered him from the shockwave - as did the body of the stadium, though Dawkins had not the time to realize it. Even so, he was nearly blinded by the flash that did reach him, and deafened by the overpressure wave that swept across him like the crushing hand of a giant. Had Dawkins been less disoriented, he might have thought earthquake, but even that idea did not occur to him. Survival did. The noise had not stopped, nor had the shaking, when he realized that he was trapped inside a vehicle whose fuel tank contained perhaps as much as fifty gallons of gasoline. He blinked his eyes clear and started crawling out the shattered windshield towards the brightest spot he could see. He did not notice that the backs of his hands looked worse than any sunburn he'd ever had. He did not realize that he could not hear a thing. All he cared about was getting to the light.
