Only when there was some resounding technical failure, or a head-on collision with an environmental or historical group, did TCC emerge from the shadows. The last confrontation of this kind had involved the Antarctic Pipeline – that miracle of twenty-first-century engineering, built to pump fluidised coal from the vast polar deposits to the power plants and factories of the world. In a mood of ecological euphoria, TCC had proposed demolishing the last remaining section of the pipeline and restoring the land to the penguins. Instantly there had been cries of protest from the industrial archaeologists, outraged at such vandalism, and from the naturalists, who pointed out that the penguins simply loved the abandoned pipeline. It had provided housing of a standard they had never before enjoyed, and thus contributed to a population explosion that the killer whales could barely handle. So TCC had surrendered without a fight.

Rajasinghe did not know if Morgan had been associated with this minor dйbacle. It hardly mattered, since his name was now linked with TCC's greatest triumph.

The Ultimate Bridge, it had been christened; and perhaps with justice. Rajasinghe had watched, with half the world, when the final section was lifted gently skywards by the Graf Zeppelin – itself one of the marvels of the age. All the airship's luxurious fittings had been removed to save weight; the famous swimming pool had been drained, and the reactors were pumping their excess heat into the gas-bags to give extra lift. It was the first time that a dead-weight of more than a thousand tons had even been hoisted three kilometres straight up into the sky, and everything – doubtless to the disappointment of millions – had gone without a hitch.

No ship would ever again pass the Pillars of Hercules without saluting the mightiest bridge that man had ever built – or, in all probability, would ever build.
