They say planes would still have to fly over London and if Boris Island were to ever open its doors, a knock-on effect would be a necessary redesign of continental airspace, which we can't imagine anyone welcoming with open airs. BA head Willie Walsh also points out that moving London's main airport across town would create a "vast wasteland west of London". It's all sounding less and less feasible (like building a floating airport in the aftershock of one of the world's greatest economic crises was ever going to be a breeze).
But Boris is carrying on with his plans and reports almost as if he, according to rumour, thinks he has a 'divine right to rule'. He's spreading the burden around though: answering a question from Caroline Pidgeon, Boris revealed he's letting poor old Kit Malthouse meet angry Kent politicians tomorrow. How nice of him.
