The taxi turned off on to another two-laner utterly devoid of traffic. They sat apart, now gazing out of the windows at their surroundings, taking in sprawling factories with steam towers belching white clouds, cranes etched against the sky, stationary since all construction here had ceased, then the bloated hemisphere of a fusion-reactor building, kilometres of above-ground pipes, with those glassy tower blocks nailing it all to the ground. Notable by its absence was any sign of life that wasn’t human. Neither trees nor grass were visible, and the only green on view glinted in traffic lights or showed on faded signs in Cyrillic declaring the environmental credentials of this place. Saul gritted his teeth, now aware that a search engine had begun riffling through identity files. Almost certainly it would find the two sketchy ones he had put there and immediately delete them.

Then would come a location trace . . .

‘Get ready to run,’ he warned, lights again beginning to jag across his vision. He should be able to deal with nearby cams and readerguns, and hopefully that would be enough.

Soon the taxi turned off again into a single lane that curved round to one side and across a bridge over one of the big highways, then down again. Thunder from above and a dark shadow drawing across, as another space plane hurtled into the sky. Even so high up, the thing seemed massive, and he remembered that standard transporter planes like that one overhead spanned six hundred metres from nose to rocket engines, and were capable of hauling two hundred tonnes of passengers and cargo up into orbit. Amazing that humans could build such a massive, complex and wonderful piece of technology, yet could not apply the same degree of logic and intelligence to building their societies or preventing their eventual decline. He watched the thing continue to rise, as the taxi drew up right beside the doors leading into the long, low Embarkation building. There was now a hollow feeling inside him, a blend of both awe and regret.

Then, suddenly, a massive disruption in the Minsk network, whilst simultaneously something exploded within the back end of the space plane, extinguishing that punctuated glare of its motors and throwing out chunks of dark metal trailing spears of smoke. It dropped out of the sky with all the aerodynamics of a falling chimney pot.

‘Mother of God!’ Hannah exclaimed.

He groped for information throughout cyberspace, hit disruption wherever he looked, then oddly found easy access to cameras positioned on high buildings, giving him multiple views of the disaster. He watched the plane trying to stay level but, with one of its rear wings tearing away, its nose came up as it descended. Another view gave him four seconds of its underside hurtling in, silhouetted against fire, until its rear end struck the building on which the cam was positioned. Back to another view of that same edifice, the plane carving through it, its position in the sky and angle of descent hardly changed by the impact, the wreckage of the top half of the building now strewn across factory complexes below. Then the plane went in like a wounded black swan descending on to a lake, churning up and spraying the lower buildings like water. As the nose slammed down, it disintegrated, becoming a train-shaped firestorm within which could be seen the burning black bones of its structure. It cut a swathe of devastation ten kilometres long.
