Blimpbot five had hauled two-thirds of its length over the Plaza when the big cylinder dropped out of its front cargo bay, almost unnoticed in the antagonistic environment that the decoy dispensers had created. It tumbled down for a couple of seconds until it was below the lip of Market Wall, then an explosive charge inside detonated. The cylinder disappeared inside a dense vapor burst of ethylene oxide that looked like a bloated smoke cloud. A second, larger explosion was triggered by the bomb’s control array, igniting the cloud.
The fuel-air fireball produced a blast overpressure only slightly less than that of a nuclear weapon.
Stig saw it. He had his eyes closed, and his virtual vision on medium brightness, but the flash still penetrated his eyelids. It corresponded to every sneekbot image vanishing. Several seconds later the sound wave crashed overhead. His arms tightened up as the concrete wall shook.
When he looked up the sky was dark again, though the rain had gone. He could see curious smears high overhead. Small veiled shapes cruised through the night, as if a flock of bats were fleeing the scene. There were no bats on Far Away. When he stood up he could see a seething column of luminous air swelling upward from the direction of First Foot Fall Plaza. He realized he’d lost contact with half of the blimpbots in the second wave. A couple that did respond were recording zero altitude with their helium cells leaking prodigiously.
“Let’s go,” he shouted at Olwen. They ran for an exit. “Keely, I need a sneekbot view of 3F.”
“Doing my best. Dreaming heavens, did that ever work better than we expected.”
Stig reached the stairs up to street level. He came out on the corner of Nottingham Road just as the rain began to sweep back again. His peripheral vision caught something falling above the nearby terrace of houses, something impossibly big, so he turned—“Holy shit!” He flung his arm around Olwen and carried her down to the pavement.
The mangled rear third of a blimpbot sank silently out of the night to smash into the houses, pulverizing the three directly underneath it. So where’s the rest of it? Fragmented solar panels, smashed timbers, slates, and long splinters of glass tumbled out of the collapsing rubble to skitter across the road.
“You okay?” he asked.
“Sure, still had my force field on.”
He looked at the fist-sized chunks of stone and jagged struts from the blimpbot’s geodesic structure that were scattered around them. They’d been lucky nothing larger had landed near them. He could hear screaming, shouts for help rising in the background.
“We can’t stop for them,” he said.
Olwen gave a shaky nod. “Yeah.”
They started off down Nottingham Road. Images were flicking back up into his virtual vision grid as Keely activated the second wave of sneekbots she had stowed around 3F Plaza. No matter which ones he pulled out of the grid, all he saw was the rubble they were crawling over.
Six blimpbots had survived. Their status reports were organizing themselves inside his virtual vision. One was effectively dead in the air, unable to move other than where the wind took it. The remaining five had all sustained a lot of damage, but they were mobile, and one of them was a bomb carrier. “Bingo,” he muttered. “We might be able to do it again.”
They reached a crossroads, and looked along Levana Walk, which gave them a clear view to First Foot Fall Plaza nearly a half kilometer away. As Stig intended, Market Wall had deflected the main blast wave upward, away from the nearby buildings. It hadn’t been enough to save the smaller houses in surrounding streets, which had collapsed; even the larger, sturdier blocks directly outside the Plaza had taken considerable damage. Fires were starting to root, burning fiercely amid the wreckage. Market Wall itself was now a thick stone circle of rubble, only two-thirds of its original imposing height.
Stig drew in his breath at the sight of it. “It held,” he murmured. “Thank the dreaming heavens, it held.” He hadn’t wanted to consider the devastation a fuel air bomb would cause if its blast wave had been allowed to spread out horizontally.
“You can’t let off another one,” Olwen said. She stood in the center of the crossroads, looking down each street in turn.
“Huh?”
“Look. Look properly.”
Stig followed her gaze. There were people everywhere. Dazed, weeping, bloodied, wandering helplessly through piles of wreckage, kneeling beside badly injured friends or family that’d been pulled out of broken buildings. Cars and vans were strewn across the road, none of them with any glass left intact; their alarms were all squawking furiously, lights flashing for attention, even those that had turned turtle. Rain and melted scraps of blimpbot fuselage fabric had combined into a weird sleet that was slowly and methodically smothering the bereaved landscape under an impenetrable black mantle.
