He banked again as they reached Monte Sano Mountain. If they engaged much farther out than the defenses on the mountain, the probes would just pick up their “dead” and continue on. The trick was to hit them so hard they didn’t have time. That was one of the key pieces of data that Shane had picked up in Greenland. The probes stopped to recover their wounded and rebuild from them. If you hit them hard enough while that was going on you could stop the whole process.
When he finally glimpsed the probe swarm, he doubted, though, whether that was going to be possible. It looked like a hurricane on the horizon.
He gave the signal for the group to bank around again, killing time until the probes got into the killzone. They came around to the north, the flight of fighters banking over Huntsville in perfect formation at no more than three thousand feet AGL, then turned back to the east. He powered down, dropping to just above stall speed, giving the probes time to get into the killbox. The lasers and missiles couldn’t fire until his flight engaged. They were, in a way, the signal for the engagement to start. And he had to wait.
He hated waiting.
A flicker out the corner of his eye made him turn. Rene was signaling that they were close enough but he shook his head. Closer. They had to hit them with a solid punch or not at all.
“Come on,” Alan bitched. “What the hell are they waiting for?”
“They have to get them to the programmed distance,” Roger said, shrugging. He was nervous as well. Even with the magnification dialed all the way back, the cloud of machines filled the sky. “The Sparrows aren’t going to do much against that formation. What they will do is slow some of the probes down. The trick is to get them to trickle in. If that whole mass fell on us, nothing we could do would stop it. But if we can get them to come in in smaller groups, and if we can destroy enough of the smaller groups faster than they can reconstruct, we’ll win. They need to be this side of Gurley for them to have a chance of doing that. We’re figuring we’re going to lose the Monte Sano Mountain defenses. But if they can slow them down, we might have a chance.”
“There,” Tom said, setting down his beer. “There it goes.”
The missiles weren’t even fired by electricity. Instead, an airtube led to an igniter switch. As he closed, Bull fired off all six Sparrows, then closed with guns. The flight of fighters had moved to a staggered formation and they banked upwards as they closed, cutting a swath across the front of the massive formation of probes. It still was a pinprick, but every pinprick helped.
The cloud of probes wasn’t as solid as it appeared from the distance. There were some probes that had spread out to the front. It was those that the fighters engaged, their ceramic ramjet rounds slamming into the lead probes and tearing them to shreds. It was also a necessity as the swarm got closer and closer. The probes were close enough together that the fighters were, as much as anything, “plowing the road” in an effort to cut through the edges of the cloud.
Bull had more than once started up a flock of birds. Generally, birds couldn’t hurt a fighter. But these birds were made of metal. He triggered his guns desperately as one of the probes lurched into his path, already ravaged by somebody else’s fire. The probe disintegrated in midair but pieces of it still slammed into his wingroot hard enough that he was surprised the jet held together.
Finally they were through the outliers and headed home. Now to see if the wing stayed on. As planned, they poured on the gas and headed for altitude at the same time. They had to get out of the way of the next line of defense.
Roger zoomed in Plasma Six on the front of the probe cloud and grunted in satisfaction.
“They’re picking up their wounded,” Shane said, nodding. “Just like I said.”
Some of the probes who had picked up enough metal from their deceased brethren had stopped to twin. They were quickly lost from view but it was apparent what was happening.
“Now to see if a solid punch works better,” Roger said, zooming the magnification back. The video camera was located on the observatory on Monte Sano Mountain and as he zoomed back he got one flash of the fighters screaming by not far overhead. Then it was as if the mountain erupted in fire.
On the 15th of April, 1950, Redstone Arsenal had become the Army’s premier rocket production and design facility. Since that time, every major category of rocket produced in the U.S. had some link to Redstone Arsenal and Huntsville. Huntsville, in fact, was a town of little but “rocket scientists.” Just as L.A. focused on the movie industry and had the byproduct of being filled with out-of-work actors, Huntsville was overrun with people obsessed by things that flew on a pillar of flame. And just as there were dozens, hundreds, of little production companies churning out small movies in L.A., there were dozens of companies that, with a little funding, could make things that went WHOOSH around Huntsville.
Starting with Rocket Ram-Jets, Roger had organized those companies into a minor rocket-building empire. And they had responded. Despite numerous shortages, there was still plenty of potassium nitrate, charcoal, carbon composite materials and resins, and hydroxyl-terminated polybutadiene (HTBP) to be had. When specific shortages turned up, here a thermocouple, there a specialized form of paper, the companies had adjusted, adapted and overcome. After all, they were rocket scientists.
And over the course of a few months they had churned out an enormous number of very simple rockets. Those rockets had only one purpose in life: deliver a small payload to a location not very far away and then die.
Therefore when the signal was given, over one thousand K type Estes rockets launched nearly simultaneously. Atop each of them was a small payload consisting of fourteen “metal mines” and a timer. Some of them met “leakers” ahead of the swarm on their way to their rendezvous with destiny. That was okay since every dead bot was a good bot. But most of them penetrated into the edge of the swarm and then “dropped” their payload. However, they weren’t done. The bots seemed to have some sense of their oncoming wrath because a few swerved to avoid the tearing missiles. But the swarm was deep and crowded. It was impossible to move too much within the swarm and just as impossible to miss hitting something. Every single missile, either before dropping their payload or after, managed to hit, and destroy, at least one bot. In many cases they hit more than one before being mangled out of functional existence. When a rocket flying at five hundred kilometers per hour hit a bot, rarely did either escape unscathed.
Of the thousand missiles fired from the Monte Sano Mountain defenses, seven hundred and ninety-two managed to drop their payload. Each of them carried fourteen “metal mines.” Since the rockets themselves had little or no metal content, the bots instantly gravitated to the mines, pulled the little metal bits out of this flying bonanza and then… died.
The effect, being watched from deep underground, was very much like watching fireworks, except by day. There was a small charge in the center of the payload that spread the mines out. This was noticeable by a brief puff of smoke. Then, as the bots pulled the metal tabs out of the mines and detonated them, there was a series of explosions, flowering outward from the smaller puff.
“Damn,” Alan muttered, munching on a handful of potato chips. “That’s cool. I wish it was nighttime.”
“Sun’s going down,” Roger pointed out. “Just in time for the laser light-show.”
